A decline in the number of wood thrushes is probably due to deforestation in Central America, a new study has concluded.

….Wood thrushes breed in the forests of the eastern United States and migrate in the winter to the forests of Central America. Although they remain a relatively common bird, the species has been declining rapidly since the early 1970’s and several researchers have suggested that fragmentation of forests in breeding grounds are playing a major role….
