It’s A Small World After All

A couple of days ago I visited the Presidio of San Francisco. I haven’t been going there regularly because the ecologist there is already monitoring those coyotes, but I went this time to check on the coyote I’ve labeled “Wired” — she had been radio-collared over a year ago. I heard she had moved in there and kicked out the previous family. This coyote indeed is a “toughy”. She is of special interest to me:  I had watched her wreak havoc on another coyote (who I’ve been documenting since her birth in 2015) and then pursue that coyote throughout the city for 6 months.

Second pair of coyotes in the Park

Initially I did not find the coyote I was looking for. Instead I found another pair of coyotes who looked surprisingly familiar. I’m trying to “place” their relationship among the coyotes I know. I generally can do so by watching visually for nuclear family similarities which I then hope to confirm with DNA analysis results.

I have been collecting DNA extracted from scat samples since 2008, to (among other things) help confirm my observations about relationships and movements throughout the city. The DNA analysis (Ben Sacks, Monica Serrano, et. al., UC Davis, 2020) has already shown that our present SF coyote population of 60 to 100 coyotes all came from just FOUR founding coyotes originating in Mendocino County: It appears that our SF coyote population is indeed inbred as I’ve noted and has not been augmented from the South.

Wired ran by — she’s radio-collared

When he looked at me I couldn’t believe my eyes. Was this Puff?

A couple of days later I returned to the Presidio and this time was rewarded with the appearance of Wired and her new mate! Wired hurried by with the male following close behind — she is obviously the leader of the pair. And then her mate turned around and looked at me. When you come across an old friend you haven’t seen in ages, in an odd place, your response might be, “Wow, it really is a small world!” This has happened to me with coyotes, and it just happened again! I could hardly believe my eyes! This appears to be the coyote I had labeled “Puff”. The label is based on his appearance and is used to differentiate him from his siblings when I write about them.

He was born in the spring of 2017 in a park that is not far off [I don’t state exact locations on this blog]. I’m including several photos of him (above) taken before he dispersed from his birthplace, along with photos of his mother and father on their territory there. I have DNA from these coyotes — I collect it right after it is expelled in most instances, so I know which coyote belongs to which sample. These will be used to confirm my visual/photographed observations. Puff has proved himself to be as much of a toughy as is Wired, having joined a brother to forcefully and viciously drive out a third brother from their birthplace in August of 2018, something I was able to observe. That’s how dispersal works.

It’s great to see Puff now paired up with a like-minded female (two toughies) and they appear to be the reigning alphas of their territory. It’s exciting to see these coyotes’ lives develop beyond their dispersal, something I’ve been able to do with only a handful of them so far. I don’t yet know what their relationship is with the other resident pair. They use some of the same territorial pathways, which I’m sure has significance for determining what the relationship is.

These two pairs may in fact be closely related. I say this, because otherwise, I believe, Wired and Puff would have driven out that second pair, but they have not. The previous Presidio pair along with their offspring were driven out. My continuing DNA study will confirm what their relationship is if I don’t figure it out beforehand.

So far, none of the coyotes I’ve been able to follow after their dispersal from their birthplaces has produced any offspring. Maybe Wired and Puff will produce the first 3rd generation that I’ll be able to keep tabs on! And there’s the possibility for a next generation in one other dispersed female I keep tabs on. We’ll just have to wait and see. Although I’ve watched yet another family through four generation (parents of parents of parents), there, the breeding pairs, one after the other, have remained stable and on their original territory the entire time — in fact for 13 years so far.

More recent movements within the city:

Among the four youngsters I’ve watched grow-up and then been pleasantly-surprised to see in other parks, are two that I’ve already written about, though I may not have used these labels: Scout and Hunter.

In addition to these dispersals, I’ve also seen family members travel large distances within the city to “pay a visit” or “check on” their dispersed youngsters (Maeve, Yote). I’ll soon be writing about a Dad who was just kicked out of his most recent territory and returned to where his youngsters were living. This male and his mate had dispersed from that territory (where the two youngsters remained), rather than the offspring (who did not leave/disperse) — it’s an interesting twist in things. Some family connections seem to be maintained over a great many years and over long distances.

By the way, Wired was in Puff’s birth-territory for awhile when he was still there. I don’t know if she is related to him, but there has been a long-standing association. I’ve also seen two other Presidio coyotes at Puff’s birth-territory. I wonder what the special tie is between these two family groups.


Endnotes: It’s very satisfying to have one’s visual observations confirmed by hard data (DNA). “Science” tends to accept only hard data, not visual data, though I have my photographs which indeed show connections. Incidentally, I do not use gadgets such as radio-collars or tags, which I think are harmful. I recognize coyote facially and can follow them that way, using sequences of photos to study any details. Except in a few instances, the coyotes I document are all labeled based on their appearance so I can readily know who they are.

Looks Like A Pup, But It’s A Mother Coyote!

Here is a mother coyote that people have been mistaking for a pup. At this time of year, after the entire coat of fur has been shed, coyotes indeed can look very small and thin, with very large ears that seem too big for their heads — just the way a coyote pup might look. This particular coyote is on the smaller side to begin with — probably under 25 pounds which may contribute to people’s thinking that she’s a pup.

Please keep away from all coyotes, be they pups or adults.

A Shaky Beginning for A Coyote Litter

Chuck Rossi was going to be posting his videos of coyotes growing up and we were all excited about it. However, this, below, was the only video posted on April 30th because then Chuck noticed that the mom hadn’t returned for a few days.

Mom coyotes frequently leave their pups for a full day, or even for several days, leaving them with enough food in the den to keep them going. The rescue group Chuck contacted decided to retrieve the youngsters, and it may have been a good idea since a coyote was found killed on the side of the Alameda Expressway about 1/2 mile away — they are assuming this was the mom.

I see Dads hanging out not far from their dens these days — that’s their job right now: they are on sentry duty to protect the dens and pups. Where was Dad in the case of this den? Dads fully contribute to raising the youngsters, but these youngsters were still lactating — could Dad have filled in here? The question is a moot one since the pups are now under the care of a rehabilitator.

No one can prepare baby wild animals for life as well as their parents can. If you suspect you’ve found *abandoned* coyote pups, stand back and watch for a few days before *saving* them. Maybe they need saving, but maybe they don’t! See: Please Don’t Rescue Abandoned Coyote Pups!

Shy Mom – Brave Mom, by Charles Wood

Janet’s post from May 4th reminded me of my Mom coyote from about 7 years ago. Janet noted that it took courage for her coyote to message a dog that in the past had chased that coyote. I agree.

My mom coyote was shy when I first ran into her. She had shown herself to me and my dog Holtz as we wandered around in her territory. I didn’t know how to communicate with Mom coyote and had some vague hope that we would become friends. She showed herself and so I decided to sit down. I did sit down and so did Mom. She seemed pleased that I had sat. However, being friends wasn’t in the cards.

Shy Mom


The Shy Mom photo is her at what turned out to be an easy entrance to her den area. She chose to stand her ground where pictured, barring Holtz and my progress into the brush. We moved toward her. She went back into the brush. I couldn’t see where she was so I went forward. She came out as soon as we stepped forward. That was a message that was clear and I left.

Mom – Braver


Later I thought I had such a good picture. I was close up to her and there was a lot of detail in it. I carefully edited it as it appears in this post. What I edited out of the photo was something it took me a couple years to notice. I had edited out her full breasts and swollen nipples. I hadn’t looked carefully. Once I did look, it fully explained to me the reason she had barred the path to her den area. Yet she had been so polite. She wouldn’t make eye contact, instead averted her eyes. Previously she would shadow us and occasionally stand out nervously in the open for a while. I decided she was terminally shy.

Brave Mom

A few months later Mom became brave. With Holtz by my side and separated from Mom by a chain link fence, Mom came up to us and did a number. Then she showed us how fit and brave she was. After that day, going just by my percepts, she was no longer shy with Holtz and me. After that day Mom gave us more of the same and then some. I couldn’t help but interpret her change in behavior as her change in mind and spirit when around us. Being friends, of course, was not in the cards that Nature dealt us.

How Much Rain Do You Think A Coyote’s Coat Can Hold?

This slideshow requires JavaScript.

Answer: In the winter, lots! Certainly more than your own soaked coat and jeans, and more than your 30-pound dog’s coat unless it’s got longer fur than the coyote’s. From the looks of it, I’m supposing you could water two small potted plants for a week if you could only transplant the coyote as a sprinkler to your yard!

Coyote coats serve to insulate them against the elements.  And the coats are fantastically camouflaged, helping them to blend into the landscape, especially during the dryer months. The coats aren’t large — they only cover scrawny, 30-pound frames, but the fur is long, reaching four-to-five inches in the winter. These coats are wonderfully crinkly and puffy, making coyotes look bigger than they actually are.

Their full coats will be shed in the springtime, at which time you can often see their ribs and hip bones poking up and visible through their skin. Their new coats will begin coming in sometime during late summer.

Shaking the rain off not only lightens the load — water is heavy — but it also serves to loosen some of the grime which has accumulated. Shaking also helps take care of the drip getting into their eyes. Oils and an undercoat prolong the time a coyote can stay dry in a downpour.

Coyotes are usually out, rain or shine, sometimes just to survey their territories and look around. Burrowing rodents must often come to the surface to keep from drowning during heavy rains, and coyotes often take advantage of this for hunting sprees.

A Mom Revelas to Me That She’s Had Pups

Here is a young mother who reveals her motherhood status to me. It was very exciting to see her! She’s two years old and she has just had her first litter.

In very young mothers, however, unless they show you their bellies, it is almost impossible to tell that they are lactating: the mammary glands are compact and don’t “show”.

On the other hand, older mothers very often do reveal their status as mothers. By the time a coyote has aged and has had several litters, the mammary glands sag more, and if you are looking for it, you can see what is going on.

Coyote Youngsters In San Francisco in January

Youngsters are approaching 10 months of age here in San Francisco. Above is a photo of one of them. They are still slightly smaller than adult coyotes, but seen alone, most folks would not be able to tell the difference.

If you are lucky enough to observe them in action, you will find that their behavior gives away their young age: they are more flighty, erratic, awkward, zippy and distrustful than older coyotes. They are curious but most likely will observe folks and dogs from behind a bush and at a substantial distance, as seen in this photo to the right.

Coyotes tend to play with their siblings, unless it is an “only child” — I’ve observed several one-pup families in San Francisco — in which case they play with a parent. Play is their main interest and occupation, and when they are together, they are constantly and joyfully playing roly-poly, pell-mell, tumble-bumble wrestle, chase and tug-of-war.

Youngsters are also good at entertaining themselves. I’ve seen individual youngsters play with an abandoned tennis ball for over 20 minutes, bounce themselves down a hill repeatedly, chase their tail — no different from your own pet.  They can also be seen practicing their hunting skills alone, though with substantially less aplomb than an adult.

Even if you don’t see a parent around, a parent is very likely to be close by keeping an eye on things, just in case a dog might try chasing. A parent will run in to its pups’ rescue if it feels the youngsters are being at all threatened. Youngsters normally take cues for their own behavior from the parent who is nearby.
