What is a pellet in terms of raptor behavior?

In terms of raptor behavior, a pellet refers to the remains of prey that a raptor regurgitates after feeding. When a bird of prey consumes its meals, it digests the soft tissues but cannot digest the indigestible parts, such as bones, fur, or feathers. These materials are compacted into a pellet, which the raptor later expels from its body. This behavior helps the raptor rid itself of substances that would not provide nutritional value while allowing it to effectively process its food intake.

The study of pellets can offer valuable insights into a raptor's diet and hunting habits, and they are often collected by biologists and falconers for analysis. This practice supports ecological studies and helps determine the health of bird populations and the ecosystems they inhabit.
