Owls are known for regurgitating, or casting, up pellets. These pellets are made up of all of the materials that an owl cannot digest from the food they eat: the bones, fur, and feathers. When digesting food, these indigestible parts get compacted and coughed back up later. Most birds pause from calling when casting, but Bruno the Eastern Screech Owl had too much to say to take a brief break. 😅 | World Bird Sanctuary
