California Condor Chick Casts A Pellet
The Hutton's Bowl condor chick regurgitated a pellet of indigestible material this morning on the floor of the nesting cavity.
In contrast to the daily casting of pellets seen in many raptorial birds, California Condors cast pellets infrequently, presumably because the species feeds almost exclusively on soft tissues and rarely ingests indigestible materials such as hair or feathers. Nevertheless, a few pellets can often be found in nests, and fresh pellets often have a greenish hue. Pellets tend to be formed exclusively of hair, although the frequent presence of macerated vegetation has also been noticed in pellets cast by immatures.
