The Bay Area canyon mountain lion and people

She’s a cautious mountain lion. She wants nothing to do with people and does whatever is necessary to avoid them. She travels through the canyon on the wildlife and hiking trails during those times when she is less likely to encounter people. At the first hint of a human, she quietly disappears into the brush. She knows when there are people nearby because they’re loud, not just vocally but in other ways. They walk heavy, the ground creaks and rattles under their feet, grasses crunch. People aren’t subtle on the trails. Although pumas avoid humans, there are exceptions. Females can be belligerent when accompanied by cubs. Like all species, maternal instinct kicks in. Another exception is when a mountain lion feels cornered.

Many wild animals, including the canyon mountain lion, venture out between dusk to dawn to find food and other resources, times when human activity is minimal. The presence of people alters the dynamics between predators and prey, changes feeding behaviors^{1, 2} and the locations for hunting, foraging and sheltering. Although some species, including mountain lions and bobcats, are naturally nocturnal and/or crepuscular³, studies are showing that wild animals are shifting their activities from day to night to avoid humans⁴. People should be mindful and time-share the canyon and other natural spaces with the wild residents, only enjoying them during the day. The night belongs to wildlife. Don’t visit the canyon at night, instead walk on the street in the evenings and at night. The street runs parallel to the canyon and is less than four hundred yards away.

Our canyon mountain lion runs from a person

On the night of August 23^rd, in our bay area canyon, the mountain lion avoided an encounter with a walker who stumbled up the trail. Most likely, he had no idea that he was right behind the mountain lion, heading in the same direction. The time stamp on the first video shows the puma rushing up the trail at 8:39 PM. A few seconds later, at 8:40 PM, the walker is captured on film following closely behind her.

Mountain lions follow their prey

Mountain lions follow their food and their favorite meal is venison. The canyon is currently hosting a substantial number of deer. There is plenty of vegetation, water, and cover for them. Until recently, it’s been a relatively safe haven for the does and their fawns. Before the puma showed up in July, the only predators that raised concern were a pair of coyotes who are regulars in the canyon.

A mountain lion will kill and eat approximately one deer a week. Our canyon lion, like all pumas, doesn’t eat the whole thing in one sitting. She first drags the carcass somewhere nearby and then caches it; covering it with forest detritus to protect it from scavengers and reduce spoilage. Depending on the size of the prey and other environmental factors, it can take her between 2-5 days to consume it. Being a typical mountain lion, she’ll stay nearby, unless frightened away, until the carcass is eaten or spoiled. She isn’t the only one who benefits from her hunting prowess. When she’s away from the carcass, other animals have a chance to grab a quick bite—coyotes, raptors, skunks, and other wildlife benefit from the puma’s successful hunt.

On August 22^nd, our bay area canyon mountain lion stalked and ambushed a fawn, one of two who was birthed by a lame, resident doe. Although sad to see, the death of that one fawn is ecologically significant. That fawn died so that others can live and thrive. Her death was not in vain—it contributed to keeping the eco-system balanced and healthy. She fed the community.

The delicate balance of the ecosystem

The presence of the mountain lion in the bay area canyon serves as a powerful reminder of the delicate balance between wildlife and human activity. Our puma plays a crucial role in maintaining the health of the canyon ecosystem. By regulating the deer population, she helps prevent overgrazing, reduces disease transmission (including Lyme disease), and provides sustenance for other wildlife. Additionally, because she is an opportunistic hunter she hunts smaller prey including rats.

By being mindful of our impact on the environment and sharing these spaces responsibly with wildlife and bay area mountain lions, we can help maintain the health of the ecosystem and its wild residents. The canyon, with its rich ecosystem, offers a sanctuary for many species, and it is our duty to protect and preserve it. One small way we can help the ecosystem is to enjoy the canyon only during the day—don’t go there at night. The night belongs to the wild ones. Enjoy the canyon and other open spaces during the day and leave the night to its rightful inhabitants.

The post Living with Mountain Lions in a Bay Area Canyon appeared first on Urban Edge Wildlife.

FelidaeFund/Bay Area Puma Project is using non-invasive methods to collect mountain lion scat for research. The excrement is used for monitoring the health and genetics of the local puma populations. Although people do stumble across puma scat and occasionally latrines, we aren’t very efficient or successful at finding them. And, sometimes coyote or another meso-predator’s scat is mistaken as having been left behind by a puma. Because trained scent dogs are more successful and much faster at finding scat then humans are, FelidaeFund recruited Finn, a smart working dog, along with her well-trained handler, Michelle for the job. Watching the team work was impressive.

Scent dog team searching for mountain lion scat

When Finn first detected the lion’s scent next to my wildlife camera at the bottom of the canyon she sprinted straight up the steep 85 degree incline, through sticky brush and tall grass until she found her prize—puma poop. The two human members of the team followed close behind her. Not wanting to slow everyone down, I waited below, my eyes fixated on my phone; waiting impatiently for texts about what the dog had found.  Finn’s sensitive nose led the team to a welcomed find—mountain lion latrines.

Mountain lion latrines

Mountain lion latrines are often found near puma kills, sometimes adjacent to a trail and/or under brush. Although, they can be within 15 feet or so from the carcass, they can also be located further away¹. Latrines can contain between 1-5 scats, but it varies widely; sometimes lions will defecate in one place several times or they’ll use it only once and then move on to another spot. According to the Mountain Lion Foundation the latrines vary in size and in mound height. After defecating in the latrines, lions will usually cover the excrement with forest detritus—this is one of the few circumstances when pumas cover². Possibly, covering the excrement near kills minimizes the possibility of unwelcomed predators, including other pumas, coyotes and bobcats from detecting the smell, being drawn to the fresh carcasses and helping themselves to free meals.³

The locations of mountain lion latrines are not arbitrary. Pumas don’t sit down to a meal and eat the whole thing in one sitting; they consume their prey in multiple feedings. Because a single deer carcass can feed a puma for a few days to a week, it’s practical for lions to make latrines close to the carcass. Covering them reduces the smell factor.⁴

A mountain lion’s favorite meal is venison.

Genetic checks

The scat that Finn triumphantly tracked down contains genetic material as well as other valuable components that provide insights about the health of the individual who produced it. DNA analysis of the canyon scat coupled with a larger sample base collected from other Bay Area locations will reveal information about stress levels of the local lions and the amount of inbreeding that is occurring because of fragmented, shrinking habitats and blocked wildlife corridors. Collectively, the information will help establish the necessity of building wildlife crossings over and under the highways to encourage genetic diversity within the wildlife populations.

Health check ups

The scat Finn tracked down also provides details about the canyon mountain lions health and the general health of the ecosystem. It reveals the individuals’ menus, if they’re mostly consuming deer or relying on other prey animals for nourishment. Analysis will also identify the types of parasites and pathogens that are harbored in the puma’s systems as well as the presence of deadly second generation rodenticides. Thanks to Finn, collecting puma scat in the canyon was easy.

Dog with a job

Finn is a working dog. She has a highly tuned sense of smell and is blessed with millions more olfactory receptors then we sensory deprived humans possess. Having roughly 300 million olfactory receptors, her scenting capability is around 40 times more acute than ours. Because of her talented nose, she is trained to detect specific scents, including scat from a variety of animal species and even scents from a wide range of invasive plants. Finn and her person work for Working Dogs for Conservation and are excellent at their jobs.

Finn’s nose led her to the mountain lion latrines

Using force free methods, a diverse species of animals, including dogs, horses, pigs and cats can be trained to be successful scent animals⁵. The training process is relatively straight forward and includes drilling holes in sturdy, identical containers. Samples of objects that carry the scent the animal in training is being taught to recognize are put in a few of the containers, while the remaining are filled with other unrelated scents. When the animal trainee stops and sniffs at the container with the right scent, she’s reinforced. Clicker training is a fun, force free method commonly used to train animals.

Finn is very good at her job. After her nose led her to the puma poop, she sat down and excitedly wagged her tail. Of course, she was immediately reinforced with a treat for each triumphant success.

Who would think that puma poop plays such an important role in finding out about the health of the local puma population as well as other animals in the eco-system? The scat that Finn tracked down will provide wildlife researchers and conservationists with important genetic and health insights about the effects of urbanization.  Analysis of the scat from the canyon as well as from other locations in the area will hopefully contribute to projects that unblock wildlife corridors and create wildlife crossings under and over highways.

Fragments of the Wild

Although 88 Acres may seem like a large area to the people who live on the rim and walk the trails, it isn’t large enough to successfully supply enough food, territory and mates for many of the wild animals who are regularly filmed there. This small wildlife oasis is only a small part of a network of other wild spaces in this suburban-scape. These natural places are separated from each other by busy roads, highways, fences and structures. In addition to these splintered, wild areas there is a large open space managed by the San Francisco Public Utilities Commission. In order to obtain enough food and to find mates, the animals have to travel between these green pockets. It’s dangerous for them; many do not survive past their first year, becoming victims of vehicles.

Share the space, avoid humans

Because of the size of the canyon, animals, including bobcats, coyotes, deer and mountain lions share the habitat with each other as well as the people who have discovered this small slice of paradise. Over the past 4 years, my wildlife cameras have recorded 1,000s of vignettes of wild animals hunting, patrolling, raising their young and living their lives along the trails that crisscross through the little wildlife oasis. Amazingly, the animals are mostly successful at avoiding people who hike, walk, jog and exercise their dogs on and off leash.

Mountain lion family

It is never predictable. Weeks can go by and only a few animals are captured on film, but then there are other times when the memory cards are full of extraordinary wildlife. Recently, the little canyon has been in for a treat. Along with the regular wild residents, mountain lions are visiting. Although we¹ regularly film pumas, this is the first time in 4 years that we are privileged to glimpse a little mountain lion family—a mom with her cub.

Lions in the hood

As a rule, pumas don’t want anything to do with humans and will attempt to time their visits to avoid us. Unfortunately, because of the increasing pressures of urbanization, it’s becoming harder for them to avoid detection. Their wild environments are shrinking, fragmenting and disappearing. As their habitats are squeezed, animals have little choice but to venture into nearby neighborhoods, seeking food, water and territory. Deer feast on plants around homes and the predators, including mountain lions and coyote, follow them. Felidae/Bay Area Puma Project conducted a study in the San Francisco Bay Area to predict the habitats that mountain lions occupy in these highly fragmented urban and suburban landscapes. The study found that instead of pumas being partial to areas with a high density of prey (deer), they prefer forested habitats that have sufficient cover that supports their stalk and ambush hunting strategies.

Human residents are seeing wild animals with increasing frequency. Recently, a home security camera located near the canyon filmed a large male mountain lion killing a female lion early in the morning and then dragging her down the street.

Mountain lions are highly territorial; males especially do not tolerate other lions in their territory. If their habitats weren’t shrinking and becoming increasingly splintered, the two may have never encountered each other. It is possible that both lions followed the deer into the neighborhood where the fatal confrontation occurred.

This may be a video of the male lion, crossing the busy road that borders the canyon a week after the deadly battle.

Usually our local mountain lions visit the canyon late at night, when people aren’t around. A study was conducted about five years ago that showed that even the sound of human voices was enough to startle them away from their meals. Confrontations with humans are rare. According to California Fish and Wildlife, there have been 19 attacks since 1984. Of those 19, three were fatal. The last fatality in the Bay Area occurred in 1909 in Morgan Hill and that mountain lion had rabies.

Although encounters between mountain lions and people are rare, it’s important to be cautious. Children should always be accompanied by adults and it’s safer to not hike alone. If you do happen to see a puma or a coyote, don’t run. Instead morph into a large, fearsome human—wave your arms, do jumping jacks and yell. Minimize your chances of crossing paths with predators by enjoying the wild areas only during the day. Pumas are generally the most active between dusk and dawn. Thousand of videos from trail cameras show wildlife activity occurring predominantly at night and in the early morning, before first light.

We are fortunate to have natural habitats adjacent to our communities as well as small wild pockets within some of our towns. Unfortunately, because of the increase in urbanization and the growing population, these habitats are disappearing, becoming increasingly fragmented and reduced in size. By themselves, they are not large enough to support and sustain healthy ecosystems—but, together they form a network. Wildlife has no choice but to travel across dangerous roads and sometimes into the neighborhoods in order to access these wild areas for food and mates. Although they want to avoid people, expect to occasionally spot wild animals on the roads, in your yards and on security cameras².

1. Years ago I started monitoring cameras in this canyon solely for the Bay Area Puma Project (Felidae Conservation Fund)–one of our scientists identified it as good location for research. After a few years, BAPP turned it over to me and although it’s still part of our research, it is the primary focus of my articles.

Wolf or fat coyote? Picture by Marilyn Krieger

Most of the alleged wolf sightings are not confirmed with photos and videos, but some are. A few people sent me pictures and my trail cameras snapped a series of excellent videos of one of these large canids.

Wolf reports

As it turns out, I’m not the only one who has been contacted about “wolves” roaming the bay area. I checked with Jonathan Young, the wildlife ecologist, at the Presidio Trust in San Francisco who specializes in coyotes and Kent Laudon, the Senior Environmental Scientist, wolf specialist for the California Dept of Fish and Wildlife. Both scientists told me they’ve received reports of sightings of wolves and giant coyotes. Young wrote me that he’s gotten calls and e-mails from locals, claiming that there are wolves and German shepherd sized coyotes in the city that weight at least 100lbs. One San Franciscan wrote him “it was certainly a wolf that I saw, believe me, I have a vacation cabin in Montana, I know wolves.” Despite these reports, Young said that coyotes are surprisingly light-weight. A few years ago he weighed a female who tipped the scale at 34 pounds. Although there aren’t many pictures accompanying the wolf and giant coyote claims, someone in SF posted a picture of one on the Nextdoor social media platform, titling it the Wolf of McLaren Park.

Wolf or fat coyote?—photographer prefers to remain anonymous

Remember the woman on her way home from the board meeting who told me that she saw a wolf disappearing into the canyon? Fortunately, he and his mate trotted by my trail cameras, triggering a series of videos. He looks out of place next to his mate, who is a typical-looking, lanky, leggy coyote. He’s large, solid and kind of fat—she is diminutive in comparison to him. He could easily be mistaken for a large German shepherd or a wolf or a hybrid until you see his face and snout.

People from all over California contact Laudon, claiming they’ve seen wolves. He always checks the reports and has found that 99% of the sightings are not wolves—they’re coyotes or dogs. But, what about the other 1%?

Wolves in California

Grey wolves are historically native to California—they lived here until they were hunted to extinction for sport and to control predation. The last known grey wolf in California was trapped and killed in Lassen County in 1924. Lassen County is a long way from San Mateo County. Did wolves live in the bay area? It is believed that they once were here. Based on anecdotal evidence from explorers in the 1800s, wolves inhabited the coastal ranges, the central valley and the western slopes of the Sierra Nevada foothills.

There hadn’t been wolf sightings in California for almost 100 years. That changed in 2011, when a wolf, fitted with a radio collar and named OR-7 dispersed from his natal pack in northeastern Oregon into our state. He was the first known wolf to venture into California, travelling as far south as Tehama, Shasta, and Butte Counties.

Since 2011 there have been a handful of other wolves who have gone on walkabouts into California, seeking mates, traveling thousands of miles in pursuit of love. A recent and well-publicized traveler was OR-93, he was the first wolf in 200 years to be seen as far south as San Luis Obispo and Ventura Counties. His impressive 1,000 mile journey ended tragically on November 10, 2021, when he was killed by a car on Interstate Highway 5.

Although wolves are gradually dispersing back into California, they have not made it to the Bay Area and they probably won’t. According to Laudon, they are forced to make a hard stop at the highways, notably I5 and I80.

Hybrids? Wolves or Fat Coyotes?

Is it possible that our local, oversized, super coyotes are hybrids? Did over-amorous dogs and coyotes have liaisons? Laudon says that there is no DNA evidence of hybridization occurring in the West between dogs and coyotes or between wolves and coyotes. Additionally, wolf and coyote encounters do not bode well for coyotes. Wolves do not tolerate coyotes—they kill them. It’s in the best interests of coyotes to avoid wolves¹.

Fat coyotes in winter coats

Wolves, coydogs or coywolves have not moved into the neighborhoods. The huskier, solid-looking canids that people are seeing are our familiar coyotes—they are well nourished and have grown thick insulating winter coats. One theory about why our coyotes are looking larger than their usual svelte, lean selves could be weather/temperature related. California has been in a drought for years. Until this winter, the coyotes that cruise the neighborhoods have been lank and leggy. It’s been a long time since coyotes have been seen with thick winter coats. This year is different—California has been drenched with rain and it’s cold. Laudon also thinks that there’s a psychological component to the sightings, that people wanting to see wolves, mis-identify the well-padded coyotes as wolves.

Local coyotes have become accustomed to sharing the neighborhoods with humans. Although they typically avoid people, they are sometimes spotted during the day, trotting down the street, looking for food and mates. It is easy for them to find nourishing food in our urban and suburban environments. Coyotes are efficient ratters, but being opportunistic eaters, they also eat garbage, fruit, dog food, cat food and unfortunately, they can target dogs and cats². It’s common to see coyotes in the neighborhoods—most look well nourished and they’re sporting thick, insulating winter coats³.

1. It’s a different story for the eastern coyote. Javier Monzon, an evolutionary biologist analyzed the DNA of 437 eastern coyotes and found that 64% of the eastern coyote’s genome is coyote (Canis latrans), 13% gray wolf (Canis lupus), 13% Eastern wolf (Canis lycaon), and 10% dog (Canis familiaris).
2. Living on the on the wildland-urban interface in the Bay Area means that residents need to expect that coyotes and other native wildlife will periodically be seen in our neighborhoods. Take proper measures to protect your pets and hobby animals. Keep your pets safe indoors. When walking dogs, walk them on a leash. Cats should not be allowed outside—the exceptions are enclosures and catios.

A scrape made by a mountain lion.

Kiosks, sign posts and community scrapes have a lot in common; they communicate important information from the posters to the community without the necessity of physical interaction. The location the pumas choose for their communication center isn’t random either. They strategically pick specific spots in the forest to convey messages to other pumas who patrol and visit the area. It also isn’t a coincidence that we perfectly aimed one of the Bay Area Puma Project’s trail cameras to record the puma action at this special place.

Mountain lion checking out a scrape

Anatomy of a mountain lion scrape

Watching videos of mountain lions scraping is reminiscent of watching movies in slow motion. The puma’s back legs and feet slowly and deliberately rake leaves, soil and twigs into small piles on one side of bared earth. Then they squat and either defecate or urinate on top of them. Vital information is conveyed about the scraper from the excrement and possibly through scent that is deposited from the underside of paws.

Location, location, location

Community scrapes are often located in places where mountain lion territories overlap and at shared borders. Scrapes are multi-functional; they warn other lions away, time stamp visits and help attract mates. This behavior is most often seen from male pumas. Because of urbanization, the available wild spaces are shrinking and the rules are changing. The size of territories are decreasing and becoming substantially fragmented by highways, residential development and other structures.

My guess is that this is affecting wildlife behaviors. Although, I haven’t found a published study about it, it’s possible that the local mountain lions are being forced to time share and overlap more of their territories with their puma neighbors than they have in the past. In order to avoid unpleasant encounters with each other, pumas may be making and using community scrapes more. Scrapes aren’t just found grouped together; pumas will also scrape on trails that they travel on.

Although many of the adult lions who visit the site scrape, the more dominant male often scrapes regularly. Generally, juveniles will check out the scrapes but will not leave their calling cards—it’s in their best interests not to announce their presence to unfriendly resident adult males.

The most dominant male usually scrapes and marks the most.

Prime directive of male pumas

Pumas, especially males, don’t practice diplomacy: encounters often lead to serious injuries and death. Because the prime survival directive of adult males is to reproduce and hunt, they habitually have a zero-tolerance policy for others of the same sex. In addition to food, males compete for a limited number of females who are in estrus at any given time. Not surprisingly, male mountain lion territories can overlap and include those of a small number of females—pivotal spots for the boys to advertise their availability for mating by scraping.

Prime directive of female pumas

Female mountain lions have different agendas than the males. Theirs is to survive, reproduce and care for their offspring until they are equipped enough to survive on their own. Usually, young mountain lions leave their mums to search for their own territories when they’re between 18 months and two years old. All of mom’s energy and intention goes into raising those precious kittens—she has no interest in boyfriends and usually won’t go into estrus until they disperse, unless a determined male kills her young with the sole intention of having her return to estrus and be ready to mate again.

Mountain lions looking for dates

Normally, after the youngsters leave their mums, females go into estrus and become obsessed with finding boyfriends. And, adult male pumas are open to the idea. It’s an all-consuming occupation. The girls visit the community scrapes, checking out the messages left by neighborhood and transient lions. They are seeking out the strongest males to mate with. Generally, the most successful boys are chosen. They are the ones who scrape the most frequently, depositing pheromones through their excrement on the scrapes. The girls readily ID them through a scenting process called the flehmen response. All felids, including our household cat companions have olfactory organs known as the vomeronasal organ located in the roofs of their mouths. Felids make a very distinctive face when they’re taking in the scent—their mouths partly open and their nose wrinkles.

It’s not just the boys who scrape, girls will too occasionally. Although they sometimes make their own fresh scrapes, when canvassing for boyfriends, they may urinate on the top of scrapes made by males who are candidates for mating. In addition to broadcasting their availability, it also helps to deter competitors. Of course they also advertise for romantic liaisons through calling.

The lines of communication are open

Although mountain lions are highly territorial and spend most of their lives alone, they still need each other to survive. For their survival as well as the species, it’s imperative that the lines of communication are open with other pumas in the hood as well as those who are passing through. Community scrapes work well—they provide ways for mountain lions to advertise for mates, delineate territories and time stamp their visits without direct confrontations.*

The post Social Distancing Mountain Lion Style appeared first on Urban Edge Wildlife.

The wildlife in the little canyon, like in other open spaces that are squeezed in by urbanization, must adapt and adjust to shrinking habitats that are increasingly fragmented by highways and buildings.

Predators, being territorial, need lots of open, wild acreage to live and hunt in. Additionally, some predators, such as mountain lions live solitary lives and in most circumstances don’t tolerate other lions. It’s a challenge for apex predators to navigate the dwindling open areas without encountering each other.

Canyon changes

At the rim of the canyon, trees are being cleared from the building sites while large equipment removes earth and pours foundations for future homes. Although the county has mandated the canyon below remains wild, the noise and chaos along with a slight reduction in acreage, is impacting the wild residents. Although the canyon still provides the animals sustenance and shelter, their routes have changed along with the times they use the shared trails.

Sharing the space

Marking is an essential way that predators, including bobcats, pumas, foxes and coyotes share the shrinking landscape. Animals distribute their pheromones/scent through urinating, defecating, rubbing and scratching objects and the ground. Through marking, individuals are identified along with their territories, state of health, age and when they passed by. Wild animals also mark to advertise for mates.

Marking helps territorial predators safely avoid each other in dwindling habitats. Perhaps marking increases with the decrease of space, enabling predators to successfully share the wild without potentially dangerous encounters.

Foxes are notorious for marking with feces in the middle of trails. The last couple of months the cameras have recorded this fox, along with it’s mate, cruising through the canyon—stopping periodically in the middle of the trail and pooping.

A few hours after the fox left his calling card, a resident coyote trotted up the trail, ran by the feces, hesitated, turned around, checked it out and then urinated on top of it, leaving his scent. Although marking is a typical behavior, predators may be engaging in more of it as they adapt to living in shrinking habitats.

Intriguing scents

Specific smells attract animals. The original “Obsession for Men” had the reputation of being alluring to felines. Lions, bobcats, jags and other felids would rub and mark areas that were saturated with it. There was a good reason for their obsessions with Obsession. The original fragrance contained civet musk scent, harvested from the anal glands of civet cats. The fragrance currently is formulated with a synthetic version of the scent and civets are no longer abused for the pheromone. The downside is that the new version of the perfume isn’t as intriguing to felids. I experimented and sprayed the stinky stuff on a couple of areas that are popular with our resident felids and canids. They all walked by without a glance or a sniff. The only reaction to the perfume was from a little boy who wrinkled his nose and wanted to know what the cloying smell was.

Pumpkin pie spice proved to be more lucrative. I sprinkled two different types of the spice on the trail. An adolescent coyote and a few deer were especially intrigued by the scent. Although last year the bobcats showed an interest, this year the cameras didn’t film them reacting to it.

An adolescent coyote was curious. He spent about 5 minutes investigating the spice.

Does were also drawn to the pumpkin pie spice. Although the cameras recorded mature bucks walking past the spiced up spots, none stopped to check it out.

Living in the hood

Novembers’ highlights wouldn’t be complete without videos of a some of the permanent residents.

Coyote 09M

Coyotes, being versatile, easily adapt to living near people, in some situations they thrive. The construction hasn’t put too much of a dent in the lives of 09M and his mate. They continue to hunt and patrol the canyon, with one visible change. 09M now only has one ear tag. It’s not known how he lost the other one. It may have been pulled out in a fight with another animal or by playing rough with his mate or perhaps he snagged it on something sharp like barbed wire or a branch.

Something has caught 09M’s attention. He held this position for three minutes before continuing up the trail.

Bobcats

The canyon’s resident bobcats consistently use the same trails for creek crossings. It’s easy to recognize individuals because the shapes and placement of their spots are unique to each cat.

It’s hard to tell what the evening catch is. It looks like a weasel or a ferret. The bobcats have been filmed occasionally catching and dining on them. It’s a mystery why this one wasn’t eaten.

Mature buck

This boy has been hanging out in the canyon for more than a year—he has an impressive set of antlers.

Banana slug sighting

The month wouldn’t be complete without a special tribute to California’s unofficial state mollusk—the banana slug. They have a tendency to show themselves during the winter months, sometimes hanging out in groups. It’s impossible to catch them on video because they move so slow…

The post November Highlights: Animals Adjust to Shrinking Habitats appeared first on Urban Edge Wildlife.

Despite the canyon being only 93 acres, hemmed in by homes and roads, it’s a complete eco-system where plants and animals are interdependent. The death of one organism means many others will live. The lesson hit home a couple of weeks ago when a small deer was killed by a predator. For 2 weeks, we aimed a trail camera at the carcass to see who benefited from the kill.  Although sad, the deer helped sustain life in the canyon, feeding a variety of wildlife including coyotes, vultures, crows and others.

The carcass provided meals for many hungry animals, including stunning vultures, crows and other raptors. Check out the impressive wings on this vulture—beautiful bird.

Most likely, Coyote 09M and his mate killed the deer. They frequently showed up over a span of 10 days to eat. Although sad, the doe’s death was not in vain.

Humor and frustration on the trail

There were also some light hearted moments in the canyon this month—mostly provided by the deer.

One of the resident bucks is dressed for the season—the first thing that caught my attention was his looking through the hole in the leaf that covered his eye. In addition to this plant bedecked boy, the cameras caught another buck with moss stuck between his antlers. Although I don’t know a lot about the amorous activities of deer, I know it’s rutting season. I’m guessing that he’s a bit frustrated and may be venting by slamming into vegetation. This video was filmed after he was rebuffed by a doe he was relentlessly pursuing.  Or, perhaps he’s using the local vegetation to scratch off the itchy velvet on his horns.

This post wouldn’t be complete without an ungulate’s nose.

The usual cast of characters

There are other wildlife highlights this month that are worth mentioning.

Coyote 09M and mate

09M and his mate are stunning. If it wasn’t for the shape of 09M’s mate’s snout and her tail, it’s easy to see how at first glance, she might be mistaken for a German Shepherd Dog. Someone recently posted on a neighborhood list about a loose GSD. I wonder if this is who she saw.

Foxes

What a treat—two foxes! The cams, rarely filming them in the canyon, recorded them 6 times in the last 2 weeks. Typically, foxes avoid areas where there are coyotes. I don’t think it’s a coincidence that the last couple of weeks the coyotes haven’t been caught by the main cameras. They’ve been hanging out near the carcass and in an area where there is an abundance of rabbits.

Bobcats

Is she pregnant or maybe she just had a full meal?

A highly photogenic bobcat.

The first few weeks of October were full of wildlife highlights worthy of posting. I hope that the last week will be as active. After checking the cameras, I left special Halloween non-food enrichment presents for the animals to find.

The post Wildlife Highlights from the Canyon appeared first on Urban Edge Wildlife.

A mountain lion named Slim

The wildlife cameras filmed her in March of 2018, the first week we set up the camera in the canyon. She was beautiful—a stunning female mountain lion walking down the trail in the rain. She made more appearances after that, usually once a month. Although the canyon was a relatively safe place to visit, she was mostly drawn to it because of the abundance of her favorite food—venison. She didn’t stick to the canyon though; she occasionally toured the surrounding communities. Neighborhood security cameras filmed her making the rounds, usually late at night or before dawn.

Slim tours the hood

Her name was Slim. She earned her moniker because her tail was thin, due to a lack of fur. A captain in the local police force who loves wildlife named her and it stuck. We compared Slim sightings, tracking her as she moved through her territory. She was a pleasure to watch. One day she walked into town, right in the middle of the residential district; a nice neighborhood with manicured lawns and sidewalks. Someone looked out their front window and instead of seeing the familiar kids riding their bicycles to school and people leaving for work, they saw a mountain lion strolling up the street.

California Fish and Wildlife, BACAT and the Santa Cruz Puma Project were called and quickly responded. Streets were cordoned off and residents were instructed to stay inside their homes with their pets. Slim was tranquilized, weighed and given a quick health check. She then received an ear tag and a tracking collar. Her health wasn’t great—she was malnourished and had mange, which explained the furless condition of her tail. After taking her vitals, she was placed on a truck, transported back to the open space and released.

Slim, the first mountain lion the cameras filmed, patrolling the trail.

Slim continued to frequent the canyon. Sadly, the canyon cams filmed her deteriorating—it was heartbreaking to watch. She lost weight and fur. The last time we saw her was at the end of July. A couple of months later she died. A necropsy performed by California Fish & Wildlife found she was malnourished and riddled with sarcoptic mange—both are classic signs of second-generation anticoagulant rodenticide poisoning. Some months earlier she must have eaten an animal who had consumed poisoned bait or ate another poisoned animal. The anticoagulant rat poison, traveling up the food chain, compromised her immune system and finally killed her.

California Fish and Wildlife released a study documenting high concentrations of second-generation anticoagulant rat poisons in predators in California. More than 90 percent of the tested mountain lions and 88 percent of bobcats have the poisons in their systems.

Enter the lion

For months the canyon was missing an important player—a mountain lion. Then about six months after Slim died, our cameras filmed a male lion on the trail. The three canyon cams caught him, sauntering up and then back on the trails. He was the largest puma I’ve every filmed.

The large lion became a regular on the trail, marking his territories by scraping the ground with his back feet and defecating in it as well as by spraying. He makes the rounds every 2-3 months and sometimes he sticks around for a few days. It’s easy to understand why he visits the canyon—it’s full of deer. It’s good he comes by—he, like all mountain lions, is important for the health of wild eco-systems. When he eats, many others do too.

Mountain lion #2 walking the trail

Mountain lions generally kill around one deer a week, which is enough food to last a few days. Lions don’t eat the whole deer in one sitting; they enjoy many meals every day over the course of a few days if left undisturbed by humans. Between meals, they cache the remains in a shady spot, covering it with leaves and debris. In theory, this makes it harder for other predators to discover the carcass and it helps keep the meat fresher. Although it may work to some degree, even I, a human with limited smelling capacity, knows when our lion has cached his meal near the trail.  I assume that our local carnivores, including raptors, coyotes, and bobcats can also easily detect the remains and help themselves to it when the canyon lion isn’t around. All eat well when a lion does.

We have footage of Coyote 09M racing down the trail with a deer head clutched firmly in his mouth the day after our lion had a successful hunt.

Like clockwork, the lion visits the canyon every two-three months. This is the last video we have of him from last week. He doesn’t look as robust and healthy as he did on previous visits. I hope, like Slim, he didn’t eat a poisoned rodent.

A couple of days after he was filmed last week, the mountain lion was killed on the highway. Although I treasure all of them, the canyon lion has a special place in my heart and I pray it isn’t him. Too many of these magnificent animals have become the unintentional victims of urbanization. Some are killed on roads and highways, others poisoned by second-generation rodenticides. Something needs to be done to stop the killing.

*Update: I needed to know if the mountain lion was our boy, so I pestered lots of people for information. It isn’t good news no matter how it’s sliced—it’s heartbreaking when lions are killed. My persistence paid off. The puma was a female: it wasn’t the canyon lion. Although I’m happy to hear this, I’m also sad.

The post Life Stories of Two Canyon Mountain Lions appeared first on Urban Edge Wildlife.

Along with the reduction in predators, the cameras have only caught a couple of woodrats and rabbits—favorite menu items for coyotes and bobcats.  Hopefully this is just a natural cycle and not a situation influenced by humans.  Wildlife, when left to their own devices, are efficient conservationists. Predators have large territories that include different areas with abundant prey. After chowing down on available prey in one area, they move to another good hunting area in their territories. They don’t eat all of the prey—there are always some that escape the hungry predators, quickly reproducing and repopulating the area over time.

Bobcats

We almost stepped into a pile of poop last week next to the primary camera. Some animal had purposely scraped and defecated in the middle of the trail, marking territory. I thought either a bobcat, fox or a Chihuahua. One of the other cameras cleared up the mystery.

Another way bobcats mark is by spraying. This is a popular spot that bobcats spray almost every time they go by it. This short trail, ends at the edge of the creek next to a clear pool of water.

Check out this bob crossing the busy street during rush hour traffic.

Wow! Impressive canines.

Bobcat walking to the creek

Coyotes

I’m glad to see that 09M is sticking around the canyon. Although the cameras film him frequently, lately, they’ve rarely caught him with his mate. It’s also been about one month since we last recorded the puppies.

Deer

A sharp, loud noise startled this deer. Turn up the sound and listen to the beginning of the video, it sounds like a gun. What do you think?

One of the canyon’s resident deer attempts to cross the busy road. She does this often, but this time is startled back by a car. Good for her, she’s cautious and has street smarts.

The post August, a Visual Essay appeared first on Urban Edge Wildlife.

Bobcat love

A couple of months before the video showed her in the advanced stages of pregnancy, the mom-to-be had at least one suitor. Although adult bobcats, like most felids, are solitary and self-reliant, they solicit the company of the opposite sex during their breeding seasons. Adult female bobcats are receptive to males for only a few days during their cycles. The whole neighborhood is aware when bobcats are looking for boyfriends because they fervently advertise for them through loud, distinctive caterwauling. In addition to long distance calling, scent marking, scraping and physical posturing helps get the word out. It’s not just the girls who are on the make, adult males also verbalize their desires and ardently scent mark in high profile spots, such as the center of trails.

Both sexes mark using urine and feces—the frequency increases with the urgency to mate. The feces and urine of females contain chemicals that broadcast their receptive reproductive state to available males. They also scrape the ground with their back paws and then urinate or defecate in the scrape. It seems that there is an increase in bobcat feces deposited in the middle of the trail during breeding seasons. Another way they mark is by rubbing objects with their cheeks—there are glands on the felids cheeks and the corners of their mouths that produce pheromones.

Typically, breeding season is between February and April, but depending on the climate and the environment, love can occur any time. When liaisons are fruitful, kittens are born on an average of 63 days later.

New life in the canyon

Shortly before her kittens were born, the expectant mom found a well hidden spot to deliver them. The birthing den was up the side of the canyon, overlooking the creek. It was in a dry sheltered spot, either in a hollowed out stump or a place protected by brush. She chose the location for safety and it was near a rich hunting area. In late May or early June, three adorable bobcat kittens became part of canyon life.

Like all felids, the bobcat kittens were born helpless, relying on their mum for food and warmth. Although their eyes were closed and they couldn’t hear, the neonates were guided to their first meals by the vibration of their mum’s purr. In addition to functioning as a navigation system, purring helps keep kittens relatively undetected by hungry predators. Predators are less likely to hear vibrational purrs, whereas squeaks, meows and chirps are readily picked up by their sensitive ears.

Life as a single parent

Bobcat mums are single parents—they must feed, protect and teach kittens the art of survival without help. It’s not an easy job to do in a dangerous environment. Although well camouflaged by their spotted coats, the little ones are vulnerable and might be found by other resident predators. Also, male bobs, including the kittens’ fathers, are notorious for killing little ones—doing so brings the female into estrus again.

Growing kittens demand lots of nourishment. Typically, they nurse for seven to eight weeks and then begin eating fresh meat.  While mom was away on hunting forays, the kittens stayed close together, not venturing far from the protection of the den. Periodically she moved them to other shelters she had previously scoped out that were safer, cleaner and had plenty of prey nearby.

The bobcat kittens learn survival lessons

The kittens were around eleven or twelve weeks old when they started accompanying their mum out on the trail. It’s her job to teach them the lessons that will help them survive in a harsh environment. They had lots to learn.

The youngsters had to be alert and obey their mum’s visual and verbal signals. Their lives depended on it. Flicks from her short tail, ear movements, body language along with chirps, mews and growls signaled when to wait, hide, follow and run. They also served as warnings as well as other communiqués. Check out this video and turn up the sound. Mamma bobcat signals visually and verbally to her youngsters to wait and then to proceed after she does a security check at the fork of the trail.

Not all bobcat kittens survive into adulthood. Our little family didn’t beat the odds. One of the three didn’t make it, possibly falling victim to a coyote. Early one morning, the cameras filmed the mom hurrying up the trail towards the den, carrying a red shouldered hawk firmly in her mouth. A few hours later, a coyote trotted from the direction of the den, clutching the same bird. After that incident, the cams recorded only two kittens.

The canyon kittens, like all felid neonates, weren’t born successful hunters. Hunting is a skill they had to learn. One effective teaching tool is play. In addition to being fun, playing with siblings as well as mom helped them develop coordination and learn the finely tuned skills of waiting, stalking, pouncing and catching prey.

When the little bobs were mature enough, mom gave them another lesson which helped develop their hunting skills. She dropped a wounded woodrat in front of them to pounce on, catch, kill and eat.

The bobcat kittens are evicted

The little family stayed together for about 9-10 months. By that time the kittens had honed their hunting skills and learned how to survive in a competitive environment. School ended, lessons were learned and it was time for them to leave their mum.  She made it clear with growls that they were being evicted—the little female was in estrus again and male bobcats were courting her. Although, sad to watch the two adolescents being rebuffed, her actions may have saved them from having serious confrontations with her male suitors. For awhile after the rejection, the siblings were periodically filmed together on the trail. Finally they dispersed to find their own territories. Males typically disperse further than the girls. Girl bobs sometimes claim areas that are adjacent to their mothers. We hope they’ve learned their lessons well and live long, healthy lives.

This year’s liaisons between the girl bob and her boyfriends were successful. A couple of months ago the wildlife cameras filmed the little bobcat again going through the stages of pregnancy. If she hasn’t already, soon she’ll have another family to protect, teach and feed. We’re looking forward to seeing her again on the trail with a new litter of kittens following close behind.
