Injured Coyote and Altruistic Behavior by His Mate

Leg or paw injuries are very common in urban coyotes — I see them all the time. Most that I’ve seen are the result of dogs chasing them: legs get twisted, pulled, or even dislocated and broken as they try to get away in an urban environment.  I’ve also seen several instances of this resulting from coyote/coyote interactions.

Before I even knew that this coyote was injured, I watched his caring mate investigate the severity of the leg injury. Coyotes apparently investigate through their noses more than their eyes: she sniffed the leg intently. We’ve all seen our canine companions sniff each other to find out about each other, and I’ve read about dogs who can actually sniff a two-degree temperature change in humans (which happens just before an epileptic episode), so this kind of investigative sniffing is very understandable. Their eye-to-eye gaze afterwards, in the photo below, appears to show that each understood what was going on.

Then the female did her best to get the injured male coyote to follow her to a safer area. She tried her darnedest: she poked and prodded and pushed with her paw, her head, and her whole body. He complained and rebelled with a gaping show of teeth, but eventually he gave in a little and went with her, even if only for a short distance. I posted a similar instance of this type of prodding to get a mate to do something, see Coyote Communication: An Example.

Shortly thereafter, always looking out for him, the female noticed active dogs nearby. She immediately hurried over towards the dogs to divert any potential pursuers (that’s her rushing off at the beginning of the video). None came his way. “Altruism, in the biological sense, refers to a behavior performed by an individual that increases the fitness of another individual while decreasing the fitness of the one performing the behavior.”[Wikipedia] She was clearly placing herself at a greater risk for being pursued while reducing his risk.

Later on there was more intimate contact between the two coyotes, as seen below, but I couldn’t tell if she was still trying to move him away from the area, or simply nuzzling him: this contact lasted only a few seconds, so I think it was simply a nuzzling.

Altruism: Helping A Sibling With Ticks On Her Ear

Just as in human families, some coyote siblings squabble, and some are truly altruistic, providing loving and unselfish help where and when needed. Here is a coyote youngster who has spotted a tick on his sibling’s ear. He spent several minutes, ever so carefully removing the tick and then bathing the area with the saliva from his tongue. Saliva has mild antibiotic qualities, so everything he did was helpful!
