A big bright moon out your window. A breeze in the leaves of trees. Have you heard a spooky wail and chatter? Coyote yelps can be a little creepy and, romantic notions of the wild spirit aside, inconvenient if you’re trying to sleep. When we read neighbor pffft’s report of recent coyote-induced sleeplessness, we thought, aha! Full moon!
Turns out, coyotes could care less about the moon:
Prairie folklore suggests that coyotes (Canis latrans) increase howling when the moon is full, yet menstrual patterns of coyote vocalizations have never been formally investigated. Thus, our purpose was to determine whether howling by coyotes is related to lunar condition. The study was conducted in July and August 1992, and from June to August 1994, in the Cypress Hills region of southwestern Saskatchewan, Canada. Coyote howling was surveyed immediately following dusk for 90-120 min, and was categorized by lunar condition. Group howling and group-yip howling were negatively related to increasing moonlight, but there was no relationship between lone howling and moonlight. These results might be explained by changes in the social behavior of coyotes with respect to foraging behavior and territory defense.
So, there you have it. Lonesome coyotes don’t howl more when there is a full moon and coyote crowds — we love the terms “group howling” and “group-yip howling” — actually howl less. Of course, this study only looked at coyotes in Saskatchewan way back in the 90s before Seattle’s coyotes broke big and got famous so Capitol Hill’s packs might exhibit a completely different set of behaviours. Howling at leaf blowers, perhaps. Yip yip yip!
