Responding to Recent Postings on Social Media: A Recap of Some Urban Coyote Behaviors and Some Explanations

This posting is a slightly revised and expanded version, with photos, of what was originally written for, and posted on, Bernalwood.com on May 27th.

We have coyotes in most of our parks here in San Francisco, and most folks I’ve spoken with are thrilled about it!  Enjoy it and respect its wildness! At the same time, there are some people, especially pet owners, who are not so thrilled. Here is some information I’ve put together about coyotes, much of it based on my own observations, as a response to concerns and comments which have appeared in some of the social media recently. This is information that applies to urban coyotes everywhere, not just here in SF.

COYOTES ARE TERRITORIAL AND LIVE IN FAMILIES

Most parks in San Francisco have one stable resident family, or a loner. Coyotes are not “pack” animals of unrelated individuals. Families “claim” territories which they “own” from which they exclude other coyotes — this is what keeps the population density down. They trek through the neighborhoods every night, during the early morning or early evening hours — and, more rarely, during the brightest hours of the day — marking their territories to keep other coyotes out and looking for hunting opportunities. Studies show that in urban areas, there is generally about one coyote per square mile — a family of 4 would require about 4 square miles. You will always be seeing the same individual coyotes in any particular area.

Although we have parks with loner coyotes, most parks have mated pairs with families. Coyotes mate for life, and both parents raise the young. Coyotes mate in January or February and produce young in April — births occur only once a year. 

The number of family members fluctuates up and down continually over time. In one park, it went something like this: 2-5-3-4-2. The fluctuation is due to new pups, and then to their dispersal or deaths. There is only about a 30% survival rate of pups during their first year — disease and nutritional issues take their toll.

When it’s time for youngsters to “disperse”, the parents will drive them out, or they may just pick-up-and-go. This usually occurs between one and two, and sometimes three years of age, and it occurs throughout the year — there is no “dispersal season”. However, the breeding adult pair will remain in the same territory over many years. Interestingly, wolves will actually kill their own kin in order to preserve their own statuses and territorial rights. I’ve not seen this in coyotes, but I have seen the altercations that drive coyotes out of their birth territories.

Cars are urban coyotes’ chief cause of death — please drive carefully! They often trek on our traffic grid — it’s often the “path of least resistance”.  A few days ago, in our Diamond Heights neighborhood, a car swerved right into someone’s house to avoid hitting a coyote during the early morning hours.

MORE ASSERTIVE OR INSISTENT BEHAVIOR

As the individuals in a family mature, some of them may go through phases of what might be called more “assertive”  or “insistent” behavior, such as: following or running in the direction of a dog. During pupping season, the assertiveness is strongest, with coyotes even approaching and possibly even nipping at a dog’s haunches. These are coyote “messaging” behaviors: coyotes want dogs to move on and to know the territory is taken. These behaviors don’t “define” a coyote, and they don’t last. Think of these as phases in a teenager’s life, or in a parent’s life — there’s an ebb and flow to behaviors for each coyote, often based on what is going on within the coyote’s individual family: Are there new pups? Is there increased sibling rivalry? Are parents having issues with the offspring, or trying to get one to disperse? I’ve seen no evidence to indicate that such behaviors build up towards more aggressiveness. Many of the more apparently “assertive” behaviors, both in juveniles and adults, are based solely on circumstances and happenstance encounters, so keep your distance.

SIGHTINGS

A substantial increase in “sightings” doesn’t necessarily translate into a spike in the coyote population, though this is what many people assume. Again, increased sightings could be due to their current family dynamics which may cause individuals to wander farther afield.

Unusual weather conditions can have an effect on sightings. San Francisco has just been through a four-year drought. Drought conditions cause coyotes to hunt further afield and for longer hours. They become more visible to humans and more prone to incidents during these times when their activity overlaps with ours. It takes 8 full months for an ecosystem to recover from a drought.

Human changes to the environment, including new construction, will affect coyotes in an area. In San Francisco, coyotes may be lingering longer in neighborhoods recently, and therefore be seen more, because of the current program of thinning and eliminating dense and protective thickets in the parks, reducing coyotes’ normal secure habitat.  Stopping the destruction of the habitat, and compensating for the exceptional weather or drought in various ways until the ecosystem has recovered, both are steps that could be taken to reduce sightings, and possible dog/coyote encounters, and coyotes’ spending the past-twilight hours in neighborhoods.

FEEDING

Please don’t feed the coyotes. Feeding breaks down the barrier that keeps coyotes wild. If they become food conditioned  — which is different from “habituation” (see below) — problems could develop, including approaching people, which increases the chances for a negative incident to occur. Feeding them also encourages them to hang around yards where people don’t want them.

Coyotes are opportunistic eaters, which means they can eat almost anything, but their preference in San Francisco is for gophers, squirrels and voles, which they eat whole: they need the meat, muscle, bones, fur — all of it — to nourish themselves properly. They also eat fruit, nuts, bugs, weak or juvenile raccoons, skunks, opossums, and possibly snakes. They prefer their whole foods over human-made foods, but if that human food is available, they’ll try it. And they will eat the occasional cat or small dog if circumstances are right — they don’t know who is a pet and who isn’t. Don’t create the right circumstances that could add your pet to the food chain. Please protect your pets by not allowing them to roam free and by supervising them closely when out-of-doors.

As top predators to an area, coyotes have helped rebalance the environment: they control rodents and some mesopredators, such as opossums, skunks and raccoons.

HABITUATION

Urban coyotes do not “fear” humans — that is an incorrect term. Rather they are “wary” of humans. This means that, although a coyote won’t flee lickety-split in fear when they see a human, they nonetheless will maintain distance and not approach us. And we, in turn, need to respect them and their wildness by keeping as far away from them as we can. “Habituation” is a normal progression in urban areas — you cannot prevent it because you cannot stop coyotes from seeing humans on a daily basis — they get used to seeing us. A habituated coyote is not a dangerous animal. In fact, the term “habituation” was first used to describe bears as being more dangerous if they got used to people and lost fear of us. This assumption has been turned on its head: scientists now know that bears who are habituated tend to ignore humans, whereas bears who have never seen humans become reactive. In Africa, to make gorillas less reactive to humans, for the tourist trade, people purposefully habituate them — they become less dangerous.

Coyotes also habituate to “hazing” tactics, which is why such tactics should not be used if a coyote is way out in left field. Scaring off a coyote should be used sparingly. It should be reserved for when a coyote has come too close to you. It is a useless tactic unless the coyote is closer than 50 or so feet to you, which generally delineates its critical distance for discomfort.

Note that “habituation” is different from “food conditioning”. When visibly feeding or hand-feeding a coyote, you are conditioning it to approach humans. Don’t feed coyotes.

THE ISSUE IS WITH PETS

Whereas coyotes don’t approach humans, dogs are a different story because of territorial issues and because of prey issues. In many ways, coyotes and dogs look alike, but coyotes and dogs are naturally antagonistic towards each other. Remember that coyotes keep other coyotes out of their territories. Coyotes are also both curious and suspicious of dogs: they may feel compelled to come in closer to investigate. Always supervise your pets to prevent incidents: the minute you see a coyote, leash and go in the other direction. Most dogs have a tendency to go chasing after coyotes. Please don’t allow your dog to do this.

Coyotes have approached dogs. If they get too close, they could either grab a small dog or “message” a larger dog who the coyote considers a threat to its territory or its personal space. They can only do this when they get close enough. Don’t let them. You can prevent an incident by keeping your dog away from coyotes in the first place, by leashing when you see one, and by walking away from it. It’s no different than when you encounter a skunk with its tail up: keep your dog off of it, and move away from it.

 IF, inadvertently or by surprise, a coyote gets too close, that is when to scare it off, otherwise just walk away without running: see http://baynature.org/article/how-to-get-along-with-coyotes-as-pups-venture-out/

Coyotes may follow dogs to find out what the dog is doing and where it is going (they do the same to non-family coyotes). If you and your dog are moving away from the coyote, and away from any denning site, the coyote soon will no longer follow. If you don’t want the coyote to follow at all, toss a small stone in its direction (not at it), and/or approach it (but don’t get too close) using your own blatantly angry body language and angry yelling. Noise alone, or waving flailing arms, is not always effective in making a coyote move — something has to move  towards the coyote. And it isn’t going to help if you are too far away. You’ve got to get within the coyote’s critical distance — at most 50 feet — and you have to be assertive about it. Walking towards the coyote while slapping a newspaper viciously on your thigh works, but tossing stones towards it is probably more effective. However — and this is a very important “however” — if the coyote doesn’t budge, it is probably protecting a nearby den site. In this case, turn around and leave. Do not provoke an incident. See the above link in Bay Nature.

It’s always best to be proactive in keeping a coyote away. The minute you see a coyote, leash up and move away from it, and know how to shoo it off effectively if it comes closer to you than 50 feet.

Note that practically all scratches or bites by coyotes to humans are due to feeding the coyote, or to an owner getting him/herself between a coyote and a pet, so don’t do these things. And, never run from a coyote: this activity actually initiates the chase response in a coyote who may also nip at your heels. They also sometimes nip at car tires when the car is in motion. The phenomena is called “motion reactivity”.

ENCOUNTERS CAN BE SCARY

Encounters CAN be scary if you are unprepared and don’t know what to expect or what to do. Please learn what coyotes are like, not what you think they “should” be like — for instance, that they don’t “fear” humans but are “wary” of them, and not that “coyotes should be heard and not seen”. By knowing their true normal behaviors, and by knowing what to do *IF* they approach your dog, you will be informed and you will not be so fearful. For starters, watch the video, Coyotes As Neighbors:  https://youtu.be/euG7R11aXq0, which will spell out normal coyote behavior and what you can do to keep coyotes away from a pet.

MANAGING COYOTES

The number one method of managing coyotes for coexistence is through human education and human behavior modification: that is what this posting is trying to help with. These have been shown to be extremely effective. The City of San Francisco has been lax in putting out signs or getting educational material to folks. Some of us have been filling the void, getting material, information and guidelines out to people, but as individuals or as small organizations, we have not been able to reach everyone. Please visit coyotecoexistence.com for specific information, and  coyoteyipps.com.

Many cities have coexistence policies — they all work when folks abide by the guidelines. BUT, as with car driving laws, even if you know them and follow them, there will be some fender-benders that might be frightening. We have fewer than 100 coyotes in the City; the number of dogs is in the 250,000s. There is bound to be an incident now and then.

The number of real coyote incidents in the City is not many. There have been less than a handful of dog fatalities by coyotes — all were unleashed small dogs in known coyote areas — all were preventable. There have been many incidents of people being frightened and reporting “attacks” on their dogs. Few if any of these attacks were reported on a questionnaire which would tease out what actually occurred. Instead, these incidents have been spelled out on the social media with warnings of doom that is awaiting us all.

Most of the sightings of coyotes have been reported as charming. But there have been some fearful encounters, and recently groups of dog owners in some of the parks have turned decidedly against them. Social media tends to perpetuate, spread and amplify the fears, and encounters are inevitably worded as deliberate “aggressive attacks”. For instance, recently, there was a report of an attempted “attack” on a dog at 5:30 in the morning. However, a lone coyote, who weighs 35 pounds, is not going to “attack” a 130 pound Mastiff… Coyotes may watch dogs, follow, or hurry in your direction for many reasons, including curiosity, or investigation. They may jump up and down because of anxiety. These are not “attacks”, nor are they “attempted attacks”. Hopefully, by learning about coyotes, we can diminish the very real feeling of fear which comes from not knowing what is going on.

Our Animal Care and Control Department has had many people report “aggressive” coyotes: but when questioned further, the majority of these reports were of a coyote just standing, or doing nothing but looking at the purported victim.

Two years ago I watched a man, straight faced, tell me that he had been frightened “out-of-his-wits” by a monster 100-pound coyote just a few moments before seeing me. He was visibly shaken. He hadn’t seen me watching the whole incident a little way down the path. The incident involved his dog chasing a coyote. The coyote turned around to face the dog. When the dog ran back to its owner, the coyote proceeded on to where it had been going. But the owner was left frightened, and justified his fright by saying it was a “monster 100-pound coyote”. If the dog had been leashed, the incident would not have happened. It happened in a park where everyone knows there are coyotes.

Not Signs of “An Escalation of Aggressive Behavior”

This post was written in response to recent postings on social media — see the posting below. It addresses fears that there has been an “escalation of aggressive or dangerous coyote behavior” if a coyote approaches a leashed or larger dog, hisses, uses frequently-used paths, or nips a dog in the haunches during pupping season. This is not so — these are not indications of progressively dangerous coyote behavior. They are normal coyote behaviors during pupping season which have to do with parental protectiveness, not with coyotes “becoming more aggressive”.

A friendly reminder . . .  Leashes in-and-of-themselves do not keep coyotes away from dogs. Coyotes do not know what leashes are and probably are unaware of them. No one ever said leashes would keep coyotes away. What leashing does is to keep the dog close to you and under your control. A leashed dog is also a calmer dog. You can control a dog which is leashed; you cannot control an unleashed dog. Most effective is a short leash, not a long retracting leash which allows your pet to wander 20 feet away from you: 20 feet away is not very close. Keeping your dog close to you, leashed and under control, discourages but does not prevent coyotes from approaching.

In the unlikely event that a coyote does approach a dog, he’ll usually do so from behind if possible. They are smart and want to avoid the dog’s teeth. They also want to remain undetected as long as possible — coming up from behind accomplishes this. This is why it is important for a dog walker to always remain vigilant — keep an eye open in all directions around you. You can stop the coyote from approaching your dog, often simply by facing the coyote, or if this isn’t enough, try scaring it off vehemently. Then walk slowly away from the coyote. If the coyote is already next to your dog, you’ll need to quickly pull your dog firmly away from the coyote while you quickly distance yourself and leave without running. It’s important to prevent further engagement by leaving — leaving is the important point.

So, please don’t let the coyote get close to your dog in the first place: an ounce of prevention is worth a pound of cure. Coyotes have nipped the rump or tail of dogs to message them if they feel their areas are threatened, usually when the dog has come into a sensitive area. This is normal, standard coyote behavior, especially during pupping season — it is how a coyote would communicate to another coyote. It has nothing to do with “escalating or progressive aggression” of a coyote. It doesn’t matter if your dog is docile or more assertive — the coyote will want to message any dog he considers a threat — it has less to do with the dog than with the space and the season. Please pay attention to your surroundings — being zeroed in on an iPhone precludes vigilance. Always, always, keep looking around. The better we understand coyote behavior, the less likely we will be surprised by an unexpected behavior, and the better we will be able to deal with such contingencies.

To put this in perspective, coyote nipping behavior is not something which occurs at all frequently, but it has occurred, which is why I’m trying to make everyone aware of it. It is exceptional coyote behavior which all dog owners should be aware of, and, just in case, be prepared for, during pupping season. Your dog is much more likely to be bitten badly by another dog than a coyote.

Also, I want to point out the incident I saw today, and which I see all too frequently: a dog ferociously pursuing a coyote. It’s fun for the dog — it’s terrifying for the coyote. The coyote ran for his life and remained as hidden as he could under a bush from the harassing dog. The owner was not even aware of what was going on until she was yelled at to leash her dog. Whereas a coyote will normally nip a dog’s rump as a message, dogs can actually maul coyotes, compromising their ability to survive: no one will help them with their wounds.

Please keep your dog away from coyotes — it’s best for both dogs and coyotes.

Please note that “hissing” is not hunting behavior. It is “warning” behavior: a “message”. Move away from the coyote as you would from a skunk with its tail up.

Coyotes take trails all the time: it is very normal for coyotes to take frequently used paths when there are not a lot of people on them. This, again, is normal coyote behavior and is not a sign of “escalating aggression.”

By the way, a nip to the tail area isn’t always a *warning* message. Here’s a video of a coyote delivering a playful/not unfriendly “please notice me” message. In this case it’s more the *semblance* of a nip — there’s no real nip here as you will see. This video is one of the first videos I took of a coyote in 2007 — well before I knew a whole lot about them:


This, below, was posted on various neighborhood internet groups  under the title: “Aggressive coyote incident on 65 lb. ON LEASH dog” . It shows lots of concern and fear for what the author thinks might be “escalating dangerous coyote activity” — this is not what is going on. I hope I’ve helped explain the activity as normal coyote behavior above.


Given the increasing frequency of coyote/canine/people interactions, I thought it would be useful for all of you – especially pet owners – to be aware of what happened tonight. Our dog Roxy is a five year old, 65 pound female golden retriever. The most docile and passive dog that you’ll ever meet. We were out for an evening on-leash walk around 730 on the path that follows the south side of Washington Blvd between Compton and Park. About halfway to Park, Roxy suddenly turned her head back and I did the same to see a coyote trying to bite her tail and hind legs. I immediately stood between Roxy and the coyote making a lot of noise. The coyote slowly backed away hissing the entire time. It took a few minutes for the coyote to back off and it finally turned its back to us when it was 15-20 yards away.
We continued east on Washington to Park. At that point, I decided to return home to more thoroughly inspect Roxy to make sure she had not been bitten. However, the coyote was laying in the grass along the south side of Washington making that path unusable for getting back home. We started to walk home using the bike lane on the north side of Washington. A motorist helped screen us such that their minivan was between us and the coyote. As we walked past the coyote, it began to hiss at us again. However, there was no further incident and, as best we can tell, Roxy is uninjured.Considering the size of our dog, that she was on-leash, and that we were on a highly traveled path next to a main road, this seems like an escalation of potentially dangerous coyote/canine/people interactions that have taken place across San Francisco.”

Playfulness of Coyotes


Being the social and family oriented animals that they are, coyotes who are “loners” — without families — often get . . . lonely!

Most coyotes eventually find a mate and live in families, but there is a time after dispersal– when they leave “home” — when they may be on their own, alone, and when they may miss the companionship they had growing up with their parents and siblings. Coyotes are often forced out of their birth families and territories by other family members. This usually happens between one and three years of age for various reasons, for example, when the smooth-running of the family is interfered with, because of growing competitiveness due to a domineering parent or sibling, because of new pups, or because of limited resources in an area. So the coyote moves out and on. Each coyote needs about a square mile of territory to provide for itself. When they find a vacant niche, they’ll fill it.

As seen in the video, this little coyote very definitely wants to engage with other canids — he’s running back and forth in an engaging sort of way, with his head bobbing up and down like an excited pony, and he even poses with his rump up and paws out front in the classical “lets play” stance which dogs use. But he’s also testing and assessing — notice that he does not fully approach the dogs who are facing him and close to their owners. He appears both excited and a bit anxious about initiating the interaction — there’s a push-pull of desire and fear.  I have seen short romps shared by dogs and coyotes, and then, the coyote is off — but the coyote may return day after day for this same type of  contact. Please beware that even a playful coyote such as this one in the video may suddenly nip at a dog which has been allowed to play with it: this just happened in one of the other parks where the coyote began to feel threatened or harassed and ended up biting the dog’s leg. We need to remember that wildness will always be part of who the coyotes are. At the same time, the coyote’s good will and good intentions can be clearly recognized.

The first coyote which appeared in the City outside of the Presidio (where they first re-appeared in the City in 2002) actually appeared on Bernal Hill in about 2003.http://www.sfgate.com/news/article/Coyotes-usually-seen-in-West-spotted-in-2633779.php, and this coyote, too, was reported to have romped with one of the dogs.

Respecting the coyote’s wildness means keeping our distance and not allowing our dogs to engage with them. When a coyote eventually does find a mate, he may feel very protective of his chosen mate, of himself, and of his territorial claim from all potential threats, be they real or perceived. He’ll do so with “warning messages” in the form of body language. Sometimes this “messaging” is conveyed assertively, as with a nip. Think about it: how else might coyotes clearly get their message across? Know what is going on, and please respect him by keeping your distance. And know how to shoo the coyote away if he comes too close to your dog.

At the same time, be thrilled and filled with awe and wonder at this wildlife returned to the City! Coyotes are fascinatingly social and interact with each other in the gamut of ways we humans interact with each other, including through playing, through a full array of family interactions which show that they share many of our emotions, and through protecting personal and home spaces from dogs who  they consider potential threats.

Coyotes have been moving into all urban areas — into what we consider “human areas”. It’s interesting because we humans have excluded, persecuted and wantonly killed this species for so long. Our presence helps keep away other top predators which is why they may feel safer living among us.

Thank you everyone for trying to understand coyote behavior and for accepting them as a neighbors! To become more aware of coyote behaviors, watch the video presentation,  “Coyotes As Neighbors”. And, stay tuned! In a new posting which will be appearing here and on Bernalwoods.com within the next few days, I’ve addressed some of the issues and hype that have been appearing on some recent social media sites.

Predator-Safe Dog Run

2016-01-14 at 08-27-38

Laurel loves her dogs, and she loves our urban wildlife, including the coyotes. She knows that raccoons and coyotes go a-trekking in the evenings, and sometimes even during daylight hours. “A predator-proof enclosure allows the family dogs safe, secure, anytime outdoor access between naps on the couch and outings to the dog park”. But the dog run was not predator-proof initially. She changed that so that now it is. Laurel is dedicated to saving dogs, raccoons and coyotes, and her creative solution is depicted in this photo.

It was after seeing a coyote trot through her front yard one evening, and reading reports of aggressive raccoons, that this San Francisco resident wanted to ensure the safety of the family’s three dogs. The pet door goes out to a ramp that leads into the dog run, which is now totally secure on the top and sides. “Our dogs are a part of the family and it gives us peace of mind for potty breaks even in the middle of the night”, reports Laurel. The dog-run’s most recent update is a black coating of paint, which actually makes it almost invisible when looking out of the solarium overlooking it.

An added benefit of this design is that two dogs who don’t get along can be let out at the same time because of the way it is partitioned. This helps with when a family member brings his/her antagonistic dog to visit while they go on a family trip. Laurel also walks dogs through her organization: Golden Gate Dog Walking, in San Francisco.

Siccing Your Dog On Coyotes Is NOT Cool

2015-12-30

Some unleashed dogs, through the negligence of their owners, run off chasing coyotes. If your dog has a tendency to get excited and wants to chase coyotes, you need to keep your dog leashed or walk in a different area. The problem is the repeat offenders: it appears to always be the same few unrestrained dogs who go chasing after coyotes because their owners refuse to leash them when coyotes are around.  But even worse are the dog owners who blatantly prompt their dogs to go after coyotes: I’ve seen this innumerable times, and I’ve heard stories from others who have recounted their observations of this dog-owner behavior. This is not cool. It might be entertaining and fun for the dog owner, but it is not so for the coyotes, nor for other folks in the park who have watched this happen. In fact, it’s illegal to harass the wildlife in San Francisco. Another variation of this human behavior is to leash their dog and then proceed to approach the coyote as close as possible.

Coexistence involves respecting the wildlife and not interfering with it. It involves keeping your distance to begin with. It means leashing and walking on, away from the coyote whenever you see one. It means advising other walkers with dogs if a coyote is out and where it is so that they can take the proper preventative precautions — it’s important to prevent all interactions by keeping these species as far apart as possible. It means understanding that a coyote might approach your dog for territorial reasons or, if your dog is very small, it might even grab your dog. These contingencies are easily avoided by keeping vigilant, by keeping your distance, and by walking on, away from the coyote. Coexistence also means knowing how to shoo one away if there is an encounter which is uncomfortably close or if a coyote approaches your dog. See the YouTube video, “How To Shoo Off A Coyote.”

Please don’t allow your dog to go after coyotes, and please let others know that doing so is not cool. In fact, it hurts everyone in the park when the coyotes are taught by this treatment that they must remain suspicious of dogs even if they are out in the distance. They are territorial and NEED to defend their space — and they are more likely to do so when provoked. To prevent inciting this instinct, we need to keep away from them. It’s not hard to do: I see folks constantly doing their part to make coexistence work. So please let’s all help those not in-the-loop to come into the loop by letting them know good/safe practices and why keeping our distance and moving on is so important.

 

Roadkill Reports of Coyotes, by Fraser Shilling

Since 2009 hundreds of volunteer observers with the California Roadkill Observation System (CROS,http://wildlifecrossing.net/california) have reported almost 31,000 roadkilled animals on our roads and highways, representing 400 species of reptiles, amphibians, birds, and mammals. Their effort has made CROS the largest system like it in the world. For certain mobile and easily recognized species, like coyotes, we can map occurrences of dead animals and start to figure out where they are getting hit most often and possibly why.

The map of roadkill coyote [to the left] is for 134 reported coyote carcasses, out of 723 reported for the whole state between 9/2009 and 4/2015. The # reported does not represent ALL occasions when coyotes were killed by cars, just a sample. Although we can’t say for sure yet, it looks like highways 101, 280, 680/84, 80, and 37 have stretches where more coyotes are hit. Please join the hundreds of CROS volunteers monitoring our roads and highways for roadkill to help protect drivers and wildlife from colliding. Feel free to contact CROS lead Fraser Shilling, just internet search him for his contact info.

Season for Confirming Territorial Claims is Now

This time of year is when single coyotes who have not yet bonded with a mate are exploring beyond their natal territories, seeking out new areas to live either because of internal drives or because they have been kicked out by their birth families. At the same time, intact mated coyote pairs and their remaining offspring with established territorial claims are on the alert to keep these intruders out.

Recently I wrote about an intruder coyote exploring an area already claimed by a coyote family. The resident coyotes’ reaction was to drive the intruder out. They did this by behaving un-welcomingly and antagonistically: chasing and intimidating by their glares, punching with their snouts and even nipping: https://coyoteyipps.com/2014/12/29/new-face-on-the-block/

People with pet dogs need to be aware that this behavior towards other coyotes may also be directed at dogs. Coyotes may be on the lookout, especially during the next few months, for any canine that they think might want to move in and claim the territory: these include highly active dogs whose owners are not close to them. Their job is to dissuade these trespassers from moving in. All incidents can be prevented by keeping dogs leashed and moving on.

Today in one of our parks, two long-time resident coyotes kept their eyes on two sets of dogs who were extremely active, not leashed, and not terribly close to their owners. In one case, a man was running with two smallish dogs which lagged far behind him. The running and generally active behavior of the dogs is what alerted the coyotes that these two dogs might not just be passing through. The coyotes at first just watched them, but soon they became anxious and agitated as revealed by their behavior: getting up, standing erect and pacing back and forth as they watched. As the two dogs and owner ran on, both coyotes bounded up to follow. As soon as the runner and dogs headed out of the coyote area, the coyotes calmed down.

In the second case, there was one unleashed dog and owner who were fairly calm physically, but not necessarily psychologically calm. The coyotes and dog could read each other and, as instinct would have it, did not like each other: all canines seem to have an antipathy for one another: foxes, coyotes, wolves and dogs.  The coyotes approached the dog within about 30 feet and there was minor but perceptible intimidation on the part of both the dog and the coyotes. I told the owner not to let his dog go after the coyotes, at which point he grabbed his dog by the collar and walked on. A human right next to a dog will dissuade coyotes from approaching.

To prevent any antagonistic incidents during this season — rare though they might be — it is very important for dog walkers to be aware of their surroundings and aware of what season it is for coyotes. When they see a coyote, they need to leash up immediately and walk on, away from the coyotes. This serves as a safety measure for both dogs and coyotes, and it is respectful of wildlife which is only following its instinctive behaviors. If a dog and coyote engage at a closer range, it can be pretty scary, because neither coyote nor dog will respond to an owner. The coyote may even message its antagonism with a nip to the dog’s haunches. If there are two coyotes, a dog may become baffled by the situation and not know what to do. The owner needs to move in and grab his dog quickly — but not if the coyote is too close to the dog and the dog is responding with bared teeth. Neither the coyote’s nor the dog’s intention is to bite the owner, but as the coyote attempts to message the dog and vice-versa, the owner could get scratched or bitten by dog or coyote. Please remember that these incidents are rare: the number of bites or scratches from coyotes to a human, usually because of this situation, amounts to about 17 a year for all of North America, whereas bites to humans from dogs sends 1000 humans to emergency rooms every single day. We all can prevent this eventuality by following simple guidelines: keep your dog leashed in a coyote area, if you see a coyote, move on and away from it, know how to shoo off a coyote if it is approaching.
