Regurgitate – to throw or pour back from, as from a cavity; the expulsion of material from the pharynx, or esophagus, usually characterized by the presence of undigested food.
Owl pellet – regurgitated, undigested material from animals the owl has eaten.
White wash – owl poop, like most bird poop, consists mostly of a white wash. The whiteness is caused by uric acid and is thought to be like urine.
Fun Facts
Owls generally regurgitate 1-3 pellets per night.
Some of the things that can be found by dissecting an owl pellet are skulls and other bones, feathers, teeth and beaks.
White wash on the ground can be a sign that an owl ate overhead and, therefore, it marks a good place to look around for owl pellets.
Rodent teeth, which can be found in owl pellets, contain iron, which causes them to be orange in color.
