Marbled Godwit

As I have previously blogged, most Marbled Godwits breed in the prairie pothole region of the Great Plains in the northern United States and southern Canada. They winter on the coasts of the United States, Mexico, and Central America.

Oddly, although Marbled Godwits are fairly common, little is known about their ecology. When breeding, they are spread out, and their nests are hard to find. These birds are monogamous and long-lived. During migration, unlike most other shorebirds, they become vegetarians, consuming plant tubers. In the winter, birds, like this individual foraging off the Rockport, Texas, beach on 19 February, consume various annelids, small clams, and crabs (Gratto-Trevor 2000).
