Have you ever heard an eerie whinny coming from the woods at night? You might be hearing an Eastern Screech Owl. Screech Owls have a variety of sounds that denote different things. Their even pitched trill, called a tremolo, is used between mates communicating with each other. They have a rattle sound that they make when agitated and a high pitched "bark" that indicates alarm. The sound that Bruno is making in the video is the whinny, and it is how Eastern Screech Owls announce their territory.

When a male short-eared owl claps its wings, it’s performing a display for a few reasons: as part of a courtship flight to attract a mate, or as a territorial display to warn off other intruding males. . . . #birdsofprey #owl #shortearedowl #instagood | Ta2020photography
