It can scarcely be doubted that the same applies to European birds; nevertheless, at any rate under certain conditions, some species such as the Blackbird (Turdus merula) and the Robin (Erithacus rubecula), may disgorge tolerably coherent pellets of insect remains.

Do Eagles make pellets?

About 12-18 hours after eating prey with fur or feathers an eagle will cough up, or cast, a pellet. A pellet is a compact bundle of indigestible material formed in the stomach/gizzard and covered with mucus. The fur or feathers in the pellet have little nutritional value to the eagle.

Why do owls produce pellets?

While owls are the most commonly known, other species rely on the production of pellets in order to digest their meals. If these birds couldn’t produce or regurgitate pellets, their food would get backed up and they would essentially die. Most teachers, students and hobbyists who dissect bird pellets use the ones produced by owls.

What bird bands are in owl pellets?

Ornithologists examining pellets have discovered unusual items in them—even bird bands that were once attached to a smaller species that was consumed by the predator bird. In the United States, screech owl pellets have contained bands from a tufted titmouse, black-capped chickadee, and American goldfinch.
