The sirens were loud and they were close by. One of the coyotes became frenzied and upset at the deafening intensity of the sound — he didn’t know which way to go and began running in various directions, as if he had become trapped, looking around for something to focus on and escape from but not finding it. Finally both coyotes began yipping in response to the siren. Yipping with sirens is normal coyote behavior — the difference this time was that the siren had come so close. I’m wondering if this yipping and howling served to focus and calm the one who had become frantic? This recording is of only two coyotes and a siren. The recording, unfortunately, picked up a lot of wind sound.
