Today I saw three coyotes out in a park before walkers or dogs arrived. They were exploring, looking for each other, hunting — all pretty casually. When the dogs arrived, they moved off to the side and up a hill to watch — and they intensified their watch of each other. People leashed their dogs, so no dog problems resulted. When these dogs left the park, two of the coyotes stayed together, wandering further on and eventually up a steep incline; the other coyote appeared to stay where it was.
More dogs passed the group of two coyotes without incident, and then, a soft fire-engine siren could be heard in the far distance. Such a faint sound doesn’t normally produce a reaction from the coyotes. But the younger of the two coyotes on the hilltop began barking in response, and then the one close by joined in. Most of the sounds on this recording are of these two yipping away. But you can actually hear the deeper and longer howl of the third coyote in the distance. So this recording is of three coyotes, though, as always, it sounds like many more voices than that.
When the howling had finished, the third coyote came bounding up the hill where the other two were seated. There were the usual frenzied hugs and kisses and then the three of them ran off. I could not photograph as I recorded, so there are no images of the howling itself. However, both coyotes which I could see remained seated initially as they howled and then walked around each other as the pitch and squeaks got higher! There are a number of recordings listed on this page, so look for the one labeled #1: THREE HOWLING.
