Two Coyotes Squeal Exuberantly After Hearing A Siren

You can imagine my disappointment when this video came out blurry — even when I refocused it stayed blurry. However, the sound is clear: two coyotes yip after hearing a siren. The other coyote initiated the yipping — that one was about 150 feet away from this one, and this one joined in. It was a very short yipping session which lasted just over what I was able to capture in the video. The same high-pitched sounds that were used here for responding to sirens, are also used as happy greeting vocalizations.

Some individuals mistakenly have thought that these high pitched squeals were the sounds of puppies and spread rumors that there were coyote puppies around, when in fact, it was just adults squealing their adult squeals. As you can see from the video, these are adult vocalizations. And, again, there were only two coyotes involved, though one might easily think that the sounds were coming from many coyotes.
