I have recently heard several reasons given for why there have been more coyote sightings in San Francisco: “It is dispersal season”, “there has been a population explosion”, “garbage being left out is to blame for sightings and for all dog related incidents”. These reasons are incorrect according to my own observations, and this has been confirmed by others who study coyote behavior. I will try to explain what is going on.
The dispersal is dependent on a variety of factors specific to the territory’s carrying capacity and to the family situation. For instance, I’ve seen a mother become intolerant of the presence of a daughter who could possibly displace her as the breeding female, therefore becoming the dominant female — the youngster was driven away by incessant attacks. A mom drove out a jealous male yearling to protect a new litter. A dad drove out a son who didn’t get along smoothly with the other siblings. A widowed father drove out a son exhibiting possessiveness of a new female. A domineering brother drove away his brother, probably for reproductive advantage.
Although I have not been able to see where these dispersed individuals go, I have been able to watch the strife that preceded the sudden departure of these individuals. The departures occurred in January, in February, in June, in April and one in November — not during any set “dispersal season” — coyotes don’t just pick up and go in the fall, nor are they driven out specifically at this time of the year. And I’ve seen intruders in established territories in early March — not in the fall during the purported “dispersal season”. Although more coyotes might disperse when the food supply is low — which would be throughout the winter in most places — this is not occurring now, in September-October, when pups are a mere 6 months old.
Although a family group can be as large as nine in a large territory, and indeed I have read in the news that a family of 9 was seen hunting together in Southern California, which would mean that the family of 9 has remained together, I have never seen such a large family unit here in San Francisco. Also, in San Francisco I have not seen a steady increase in the number of coyotes over an extended period of time in families within their claimed territories. I have seen constant fluctuations in coyote populations in these territories — territories in our parks and golf-courses. All of these territories still have only one family unit, with populations which have remained incredibly stable. The fluctuation over a six year period in one family ran like this: 2 -> 3 -> 2 -> 5 -> 3 -> 2. This year, in one of the parks, just one pup was born, which suggests to me that saturation might have been reached in their numbers.
Since coyotes appear to need about a square mile of territory per coyote to support themselves, and even if they needed half this amount of land, San Francisco will never be “overrun” by coyotes. There has not been a “population explosion”. Coyotes population numbers are regulated depending on the resources and carrying capacity of the land. When the land no longer provides for their needs, they will no longer increase their numbers. They don’t need “human management” to interfere with this.
“I do agree with you that there isn’t any set dispersal season and I would say that early fall would be very early for young pups that are just getting to 6 months old. I would agree that it occurs any time of the year with some delaying dispersal to form packs with their parents/family, but I would also think that winter [on the East Coast] would be the normal time for the majority to disperse due to food issues in an average territory as well as sibling interactions which often seem to be the largest indicator of dispersal.” Jon Way
Coyotes-seen-in-the-neighborhoods recently in San Francisco is not an indication that there has been a population explosion. Coyotes “trek” every single night through our neighborhoods. They always have. This is normal, healthy, coyote behavior. They are marking their territories and searching for good hunting areas. They’ll mostly dig for gophers and voles — these are their staples here in San Francisco, but they also eat fruit, and larger prey if it presents itself, and they’ll eat food left out in your yard. If, as they are trekking through, they find a cache of gophers, or even skunks, raccoons or even a free roaming cat if one should appear opportunistically, they will keep returning to the area for a while in hopes of finding more of the same bonanza.
An increase in the number of sightings could be due simply to more people in the city to notice them, more folks out of doors in the city, more internet use, and more social media such as Facebook and Nextdoor, and to there being more dogs than ever before: all coyote issues revolve around pets. It could also be due to the drought, as proposed by Mary Paglieri, which might be diminishing their gopher supplies, causing coyotes to expand their home ranges and hunt more during daytime hours. Coyotes are not overrunning the city.
“With lack of food and drought I could definitely envision [coyotes] either expanding their territories or probably more likely, within their normal territories, spending more time than average near people and houses looking for food and water. There is a lot of individual variation in this and regardless of drought, etc, it only takes a couple of individuals (maybe 1 pack) in a given area to become more visible – which to us means being more active during the day vs the night – to make them appear that they are more numerous…. but yes, over time the territoriality of a pack (3-5 individuals on average) would prevent them from exploding (or whatever term is used) in numbers like many people (and managers) mistakenly believe.” Jon Way
In one of the parks here in San Francisco, two small dogs were grabbed by coyotes within a month of each other. The city has told residents that all coyote incidents, including these, were due to feeding coyotes, in this case leaving garbage out. The thinking seems to be that the coyotes are being drawn by the garbage into the more populated parts of the park where they are becoming more familiar with dogs and people, and that it is because of this that they grabbed the two dogs.
But garbage lying around does not cause coyotes to grab dogs. Whether there is garbage or not — and garbage has been in these parks for years without incident — small dogs may very well be taken unless the owners are vigilant and follow the guidelines. These incidents were not due to garbage being left out. They were due to the opportunistic behavior of coyotes which will continue whether or not garbage is out in the parks. In addition, these incidents were not due to habituation of the coyotes. In an urban setting, ALL coyotes become habituated — they become used to seeing people. Habituation does not cause coyotes to approach people. However, habituated or not, coyotes could very well approach little dogs who are not intensely supervised, be they on or off-leash if they think they can get away with it. And, coyotes may message larger dogs, and they may even message leashed dogs. You can prevent this.
What actually is habituation? “Habituation is a natural process by which an animal adapts to its environment and the stimuli within that environment. It is the diminishing of the flight response due to repeated stimulus which is inconsequential. Passing interactions between coyotes and people/pets are constant and inconsequential for coyotes: humans are not seen as competitors nor as predators to a coyote.” You indeed CAN condition and shape coyote behavior through food conditioning, but this is not going on in the park: no one is using food to make the coyotes come down and grab a dog. Note that food conditioning and habituation are totally different phenomena. Mary Paglieri.
Both little dogs were taken in a park known for its coyote sightings. One of the little dogs — a 7-pounder — had been allowed to run ahead of its owner on a wilderness trail which had a small sign stating that it was an on-leash only area. The little dog ran into the woods in pursuit of a coyote and was grabbed. Why hadn’t simple common sense been exercised? Why hadn’t the owner listened to folks warning him? — many folks had warned him. And most importantly, why was not the sign more prominent?
The other dog survived his ordeal. The owner visited a park at 6:30 in the morning. As he unleashed one of his two little dogs, he looked up to see a coyote right there in front of him who grabbed one of the little dogs. There were signs and there had been warnings, but the owner stated, after the fact, that he thought it would never happen to him. Vigilance, and a quick scan could have prevented this incident. Also, folks need to be aware that coyotes are diurnal and therefore may be out at any time of the day, and that their prime hunting and trekking times include the hour or so before dusk and the hour or so after dawn. Small dogs are least safe at these times when few other walkers are out.
If folks don’t want to learn about coyote behavior, and if they can’t watch their dogs more carefully, might it be a good idea to put in a fenced area in this particular San Francisco Park? The fenced area would keep dogs, both large and small, from running off after coyotes into the wooded areas. Although it wouldn’t insure 100% protection, it would discourage and deter coyotes from the area, and with humans around to shoo coyotes off, it could increase little dog safety immensely. Folks would still need to be vigilant.

Please check out Geri Vistein’s new book, “I Am Coyote”, available through Amazon beginning on October 9th! Congratulations, Geri!
The brief review on Amazon states the following: “Coyote is three years old when she leaves her family to seek a home of her own and a mate to share it with. Journeying by night through a Canadian winter, she doesn’t know that her search will become a 500-mile odyssey. Nor can she know while enduring extreme cold, hunger, and harrowing brushes with death that she and her descendants are destined to play a vital role in the forests of the eastern United States, replacing wolves (exterminated a century ago) as the keystone predator the landscape desperately needed.”
“Combining rigorous science with imaginative storytelling, I Am Coyote reveals the complex outer and inner lives of coyotes. We are not the only sentient beings on this planet; we are not unique in experiencing love, fear, grief, joy, and acceptance. This magical story will change the way you think about the animals with whom we share the world.”
A few more reviews are in order:
“This is not a book about ‘a species of animal’ and what ‘it’ does. Geri Vistein takes us so deep into Coyote’s skin and behind the eyes and nose that she reveals for us the intricacies and perceptions of creatures who lead lives among us. This is the right perspective for understanding who we are here with on Earth. Vistein has chosen one of the absolutely most wondrous fellow-creatures in America to make our introduction.” –Carl Safina, author of Beyond Words: What Animals Think and Feel.
“For wild predators every day is a drama of life and death – Geri Vistein uses these daily theatrics to tell the tale of the colonization of eastern forests by coyotes. The story invokes the spirit of Ernest Thompson Seaton’s classic “Animals I Have Known” but is more firmly rooted in modern scientific findings not available to Seaton”. Roland Kays, Ph.D., Professor, NC State University, Dept Forestry & Environmental Resources, Lab Director, NC Museum of Natural Sciences.
“Vistein, a carnivore biologist, tells the story of one of the early migrants from the coyote’s point of view and asks readers to consider coyotes as “intelligent, sentient beings” able to experience “fear, joy, affection, loss, grief, puzzlement, and acceptance but never anger.” Vistein’s writing is impassioned and poetic as she tells of the female Coyote who travels east—facing danger from traps, traffic, guns, and dogs—to finally find a refuge in Baxter State Park. When Coyote finds a trapped coyote, she helps him to free himself (he chews off his paw). They become mates and, as seasons and years pass, raise four litters of pups. Readers learn about the complex social structure of coyotes (previous years’ siblings help out) and that life as a wild creature is often tragic—though Vistein balances the harshness of death with a wider, natural-order-of-things perspective. A sensitive, passionate story told from an intriguing point of view”. -Kirkus Review

A new pile of debris, consisting of cardboard pieces in a pile, caught the attention of this 3-year-old female coyote as she headed to her favorite hideout retreat for the day. She approached the pile, as though she were hunting — slowly and carefully, almost tip-toeing in. Then, she turned her head from side to side as she listened for what kind of sounds the new “object” might make. The pile remained silent, so she decided to investigate closer. She snuck up, ever so carefully and hesitatingly, and attempted grabbing a section of the cardboard in her mouth. This caused another piece of cardboard to shift and move where she had not expected movement. She immediately flinched back, backed up, and then stood behind a planter, keeping an eye on the pile of cardboard. Nothing happened, but it wasn’t worth the risk to explore further. Her suspiciousness ruled supreme, and she skedaddled lickety-split away from the cardboard, around some bushes, and out of sight.
Coyotes are very aware, wary, and suspicious of any changes in their known environment. In this case, someone had dumped some cardboard outside their home. Even though the new material made her uneasy, the coyote was curious and checked it out. The unexplained movement in the cardboard served to seal her suspicions and she decided it was not worth the risk of further investigation. She’ll avoid the area for the next little while and then eventually get used to it, and go on as before. However, if I wanted to dissuade her from coming around again, all I would have to do is move the pile around. She would notice the change, and because of her innate suspiciousness, she would avoid the “possibly dangerous” pile.
To discourage coyotes from visiting your yard, you can tap into this coyote behavior. Place large objects in your yard. The change will make them uncomfortable. They may “check things out”, but they will move on and avoid the object. Every few days, rotate the object or substitute something different. Soon, the coyote will look for another, less disturbing pathway! We have Mary Paglieri to thank for making us all aware of this method of dissuading coyotes from visiting our yards regularly.

In San Francisco, coyote dens were abandoned by their occupants long ago — dens are used for birthing and for the first months afterwards before the pups move around much. After that, although coyotes return to the denning area, they sleep out in the open and in various locations. Here are two dens, no longer being used, which I saw on the same outing.
This first one shows an opening which has closed up a bit with debris due to non-usage. It’s a hole dug into the root system of a fallen tree. When it fell, the tree was sawed into pieces and left there. The upended tree left openings through the partly buried root system in the ground which the coyote then dug even further for its use as a den. The landscape it is found in is a small redwood grove, as seen above.
The second den, below, is one which was entirely dug out by animals. It is located in a scrub area which faces a protective forest. It may have been originally built and used by another burrowing animal. When the coyotes found it, they expanded it for their own usage. This den, as opposed to the one above, has an opening that has caved-in and opened up. The opening probably had some kind of foliage hiding it when it was in use. It opens to the top and side of a hill and goes way back, with a ceiling which is about a foot under ground level. We could have found out more about it by destroying the den, but our aim is always to interfere as minimally as possible: hopefully a family will be occupying it next spring!
Every den is different. In urban areas, coyotes have been known to build their dens near buildings, under porches, close to roads and even in parking lots! Last year in San Francisco, one mother had her pups under a parked car in a driveway right off Capp Street at 24th Street, which are busy and noisy streets. This year a coyote gave birth in one of the public restrooms of Golden Gate Park!

This article certainly presents an over-dramatized story: “Predators are lurking in the darkness”, “slinking through alleyways”, “popping out of the shadows” — aren’t these fear-provoking phrases? “A dozen sightings” — yes, but of the same three coyotes. A “pack” implies danger — the truth is that coyotes run in families, not packs, and the largest number seen together in this area has been three.

This observation occurred way back on June 19th, but I never got around to posting it until now. Dad was doing his duty when he came out at late dusk to check things out for safety. The pups themselves were still too young to be brought out into the open — they were still only two months old. He must have been making sure the area would be safe for Mom. Mom coyote was still lactating, and her survival was necessary for the survival of the youngsters. Coyote family members watch out for each other.
Dad came to the crest of a hill and looked in all directions. Mom stayed at the bottom of the hill assessing the situation for herself and looking towards Dad for any signal of danger he might give her. Dad indeed had heard some voices and saw SOMEthing, and Mom knew how to read his body language. She hurried back to the safety of the bushes and he followed soon afterwards.
I went looking for what the disturbance might have been. I only had to walk a few paces to where, because of the darkness, I could barely make out two fella humans sitting on the ground by some rocks next to the path the coyotes would have taken. They were talking in barely audible soft, hushed voices. I don’t know if Dad coyote had heard them, smelled them, or seen them. I myself had not heard them or seen them (or smelled them!) in the quiet of the evening, and would never have known they were there if it were not for the revealing coyote behavior — the same behavior that Mom coyote could read about Dad.

There’s the siren, then the yipping begins and immediately one of the coyotes walks towards the other — they like yipping together — and they continue their chorus side by side. When they’re through with the yipping, the female scratches some bugs on her body, and the male snaps at the bugs in the air in front of him. Finally the male coyote, as he hears dogs barking in response to his yipping, sits to watch the activity in the distance. After a moment of watching, these two continue their trekking.
