What is this? Looks like remains of some animals. That is correct, these are the pellets (or castings) of a Long-eared Owl. They consist of undigested fur, feathers, bills, claws, teeth, skulls and bones of the prey animals. Why would you buy this? For science, of course! Students can learn a lot about food chains/webs, owls, and more through the investigation of Owl Pellets. Don’t worry, they aren’t slimy or smelly, they are dry.
