Nest sanitation is important when raising chicks, so rather than defecate in the nest, young birds produce a packet of waste called a fecal sac. Some parents carry this sac away from the nest before disposing of it; others simply eat it. Young birds have highly inefficient digestive systems, and the fecal sac still contains valuable nutrients for the parents. • This video accompanies Chapter 11, Breeding Biology of Birds, Handbook of Bird Biology 3rd Edition from the Cornell Lab of Ornithology and Wiley Publishing. • http://birdbiology.org • David A McCartt/Cornell Lab of Ornithology/Macaulay Library/475922
