male. On their wintering grounds the males have territories in the forest and the females in more brushy habitat. Kricher and Davis have investigated winter site fidelity among migrant species in southern Belize and have shown that such species as the wood thrush, ovenbird, Kentucky warbler, and gray catbird occupy exactly the same locations from one winter to the next. Although these birds migrate north to nest, they return in the fall to precisely the same local wintering area used the previous year. The genus Wilsonia is named after Alexander Wilson (1766-1813) Scottish/US ornithologist and author (American ornithology, 1808) Not to be confused with the species designation wilsoni which depending on the genus can refer to Thomas B. Wilson, Scott Burchard Wilson, or Captain M. Wilson.
