The gizzard in an eagle not only performs the task of primary digestion, by grinding up harder to digest food, but also forms pellets of indigestible substances. Within 24 hours of ingestion these pellets form and travel back to the mouth where they are vomited out and expelled. The usual substances contained in them are hair, feathers, and sometimes bone. Can someone explain to me why a lead fragment would not be included in the substances that an eagle cannot digest, and would not be expelled like all other indigestibles within 24 hours or so?
