In one of the wetlands near the Pacific Ocean (Tijuana Estuary), we saw three Yellow-crowned night herons. This one seems to have taken a nap before the night's hunt. Its food consists mainly of various crustaceans, especially crabs. The Yellow-crowned night heron occurs from the southeastern United States down to the coasts of northern South America. Those that breed in more northern areas spend the winter in the southernmost United States, e.g. in Florida and southern California. Interestingly enough, both the length of the bill and the breeding season vary with the crustaceans found at the breeding site!
