It’s Mating Season, and things don’t always work

Right now it’s mating season for coyotes.  This is a once-a-year event, and actually distinguishes coyotes from dogs who have a twice-a-year reproductive cycle. Here is a short summary of the process.

An unattached female usually has several suitors, and it’s the female who then chooses among them: see Coyote Courtship by Walkaboutlou — in this story, the fella who brings her a gift of a rabbit is the one who wins her!! Then, usually, the pair remain together for life, but not always! See “Till Death Do Us Part?“.

In most instances, when the female is in heat, the male will closely and carefully guard her and stay with her. The earliest I’ve seen females reproduce is 2 years of age. The earliest I’ve seen males reproduce is 3 years of age. I’ve heard of them reproducing at a younger age, but I have never seen it myself.

Interestingly, coyote males only produce sperm at this one time of year. Producing that sperm is a two-month long process called spermatogenesis. They, too, become fertile at the same time the females do, and have only a very short window of opportunity in which to ‘perform’. It doesn’t appear that this “system” has limited the number of coyotes around!

Mating in coyotes involves a “tie”, which is how you know that it didn’t happen in the above video — the process was not completed in this video. The tie is where both coyotes become “locked” together for as long as 20 minutes — back end to back end. You can imagine that they are extremely vulnerable during these 20 minutes. In the video above, the male mounts the female, but obviously something isn’t right. He turns around to examine the problem or fix it, then they move out of the range of the camera.

As the time of birth approaches, the female will dig a den or find an appropriate alternative (expand another critter’s hole, find harborage under a rock or fallen tree trunk, etc.). During birth, she’ll want to be left alone, so the male waits or guards the area outside where birthing is taking place — I’ve seen males guard like this for about a week. See The Birthing Rock. During this time, the male often brings food to the female. Then, I’ve seen coyote mothers first emerge from their dens anywhere from one day to almost a week after they give birth.

Pups are born after a 63 day gestation period. I’ve seen as few as one and as many as seven pups born, with an average of 3 or 4. Of that larger litter, only four survived to disperse or move on. Survival rate can be as low as 20% in the wild, but it appears to be higher in urban areas. Pups are raised by both parents.  Lactation occurs until about June. As the pups are being weaned they are introduced to regurgitated food from their parents which eventually will be replaced with more and more solid food in the form of dead rodents and then live ones until the pups get the knack of hunting for themselves. However, I have seen a father coyote still regurgitating for his fully yearling pups!!

Pups are kept well hidden and as “secret” as possible until they attain some ability to take care of themselves.  Then they hunt together in twos or threes and eventually the youngsters will head off on hunting and explorational forays of their own. They disperse sometime between one and two years of age, usually. In the meantime, for the 1-2 years before dispersal, they live very full and rich family lives, with interactions between them, along with feelings that rival our own.

‘Till Death Do Us Part?

Introduction: That “coyotes are known to mate for life” is something most of us have heard. In fact, I think it’s the only reality I’d ever seen in 13 years. However, as events in one of my families unfolded in early February of this year, I had to question this. My own perception of the turn of events came in bits and pieces and in fits and starts as revealed through a field camera which was out only at night, and not always then. My own desire for this pair-bond to be everlasting caused me to latch onto any details to support my belief, and herein lies a sort of soap opera aspect to the story which I weave into the ending. My ‘hopeful speculations’, along with background history have grown this posting into an unusually long one — a mini-tome! Yikes! 

Please know that every single one of these photos, as all the photos on this blog, were taken as photo-documentation at the time these events occurred. I don’t substitute a photo from another time or place that might simply “do”. What you see, and what you read, are authentic and concurring.

Background.  The years immediately leading up to this story serve as an important point of reference for what comes later, so I’ll sum those up here.

Distressed Barking By Mother Coyote Due to Presence of Dogs

Parent coyotes are especially edgy at this time of year — it’s pupping season.

As this mother coyote foraged behind some low bushes, dog owners with their mostly leashed dogs walked by on a path about 100 feet away: they stopped and looked at her, though it might have been better if they had just walked on. None of the dogs approached her, though they might have communicated some kind of negativity through their facial expressions and body language. The coyote apparently didn’t like them looking at her, or she didn’t like their negative communication. OR, the dogs may simply have been too close for comfort.  I was concentrating on her, so I couldn’t see what the issue was.

Note that she begins her complaining with little grunts and heaves: it’s an emotional and distressed reaction.  As she initially grunts and heaves, she hasn’t decided to go all out with her barking. But soon, she lets loose. All the dog walkers “got it” once I explained to them what was going on: that this was an edgy mother and coyotes don’t like dogs around them. The walkers and their dogs moved on, and she soon quit her howling and then retreated into the bushes.

Her own mother, too, engaged in this exact same type of barking: it is a distressful bark and only occurs when these coyotes feel harassed or intruded upon by dogs. This type of barking is both a complaining — letting everyone know how she feels — and a communication of standing up for herself, though you can be sure that if a dog went after her, she would skedaddle quickly. The barking session shown here lasted only about three minutes, but I’ve listened to one that lasted well over 20 minutes.

Courting and New Bonds

It is again breeding season, when unattached coyotes look for partners who will become their lifelong mates. These two coyotes appear to be a new “couple” or “pair”, or at least they are headed in that direction. The male has been following around after the female, at a comfortable distance, without crowding her, and even looking disinterested at times, but always only a few paces away!

The male is totally solicitous of the female, and ever so careful not to annoy or upset her. He watches for, and is alert to, any sign of displeasure from her. She is the queen. She, on the other hand, is much less interested in him, it seems. But she is his “chosen one”, and if she consents to his advances, they will become partners for life.

Breeding Season: Smells and Walking on Eggshells

This is all about powerful enticing odors — exuding and absorbing them. Attendant behaviors include edginess and short tempers. Odors are left anywhere, but especially on existing odors, such as where a dog has urinated. Odors are absorbed by wallowing in them and sniffing them.

Behaviorally, there is a decisive tentativeness during this time of year as a male and female approach each other. When HE comes over to sniff her, his movements are slow and as inoffensive to her as possible. The minute she shows any signs of flinching, he stops dead-still and waits for her to finish her reaction. He reads every detail of her movements. He is totally accommodating and ever so careful not to annoy.

For her part, she likes his presence — after all, she is walking with him. But she has let him know that he better watch himself — she appears ready to react to any misstep on his part. She rolls in his urine and allows his closeness — if he is careful. They read each other well. She’s been testy recently and he is absolutely walking on eggshells because of it.

I’ve numbered and annotated the 32 slides to explain what is going on in each one.

A “Tie” in Coyotes

Coyotes literally become “tied” together during mating. As you can see from this video which I found on youtube, it puts them in a very vulnerable position and could be dangerous for them if there were larger predators around.
