Hi Janet, I have been looking at your website and very interesting blog—love the YouTube videos of coyote vocalizations.
I live on Whidbey Island and am fortunate to have coyotes around me on my 5-acre property–even last summer having a litter of 4 pups born on my property who used to frolic in my heath and heather near the house.
Yesterday, I found two large incisors that might possibly be from a coyote. Last week, there were at least a couple yipping it up and barking just outside my home in the landscaped area around the house. I also found a tuft of coarse grayish hair that looks to be the color of one of the pups that lives in or near my property. My question: do coyotes attack and kill each other? I am hoping that nothing has happened to either the mom or one of her pups that regularly hunt on my property.
A little about me: I have a Master’s in Psychology, with an emphasis on animal behavior. Hence, my interest in coyote behavior.
I love having the animals around me and as I work in my landscape, they sometimes will sit and watch me or as with the pup, lie down with their legs outstretched and watch me for a brief time. I think they are as fascinated with me as I am with them!
Thanks for championing their protection. They have a vital place in the environment and they help keep the rabbit population in my area slightly reduced.

Battle wounds from territorial conflicts
Hi Cindy!
Thanks for contacting me. So glad you are enjoying, and hopefully learning from, the blog and videos! And so glad you are a supporter of the wildlife, especially the coyotes, around where you live. Lucky you to have the acreage that can include a coyote family!! :))
My knowledge of coyotes killing one another is limited. I have never seen it happen.
I have seen vicious fighting: https://coyoteyipps.com/2018/10/06/territorial-fighting-can-be-vicious/ and https://coyoteyipps.com/2019/04/02/adversity-continues/.
I’ve seen tail-pulling which definitely would yank some of the fur off — in this case, when two siblings were driving out a third sibling: https://coyoteyipps.com/2018/08/09/sibling-best-friends-become-arch-enemies/
And I’ve heard of two instances where angry coyote rivals on adjacent territories and probably vying for expansion into the other’s territory, have killed the pups of their adversaries, but I have no way of confirming this — these “stories” were of “intruding” coyotes doing the harm, which is pretty unheard of — except these two unconfirmed stories I’m telling you about.
I believe a coyote will fight another coyote if that other coyote puts up continued resistance to leaving a territory, but in almost all instances, after a very initial encounter (with minimal damage inflicted) and due to reading each other’s body language, both parties know who will win the battle, and the weaker individual flees the situation rather than endanger his/her life through intense engagement.
I wrote a friend, Lou, to get his insights on your question — he’s out with coyotes constantly in his ranching work. He says,
“I personally have never seen or heard of a coyote killing another. I suspect there are occasionally intense maulings. Usually, the loser quickly runs, or appeases and creates safety/space.
I have also seen where coyote pairs seem to have lost pups to wolves and definitely dogs. Perhaps a dominant coyote pair may kill intruding pups, but I’ve never seen this either. Could it happen? Likely. But my impressions of coyote is they have moments of fierceness but it’s [just] moments. They flee quickly when they lose a fight and they are usually quick to stop attacking when a submissive signal is given.
If it happens..it would be rare. The situation would be unique and unusual. PS-that being said, I have seen coyote with tremendously scarred faces indicating big battles. Whether it came from wolf or dog or coyote i couldn’t say. But as you’ve seen they can fight fiercely.
My impression is wolves and dogs quite often kill each other. Coyote quite often fight but then one runs and it’s over. (Usually is always my go to. Coyote always surprise)”
Dogs can and do easily kill coyotes, and it’s very possible that a dog came through your area. :((
Right now it’s mating season. Males indeed are guarding/protecting their mates. Those hormones are powerful incite-ors (I made up that word, but I think it makes sense), as can be seen by watching videos of the animal kingdom. At the same time, territorial ownership is being confirmed and even challenged.
Please let me know if this helps at all. Also, if you have any stories you’d like to share on my blog, I would love to post them! It helps round-out the picture to have more people in different situations writing about them. Please let me know! :))
Janet
