Howling Coyote - Yellowstone
from flickr.com
This coyote was found near Specimen Ridge, on a bitter cold -12F degree below zero day. His pack-mates are just below the ridge, between him and the hills in the distance. The howling session lasted for over twenty minutes.
Communication by howling or vocalization is common among all members of the Canidae family. Studies of the various North American wild canids have identified a large variety in the types and variations of vocalizations used by these species for communication. Most of the research conducted on canid vocalizations has focused on Canis lupus (wolves); there are very few studies that have explored the potential information content found within coyote vocalizations.
