When we first moved our current location in Nobleboro, 40 years ago, I could usually hear three wood thrushes from our deck every summer. Then there were one or two, now none. There has been little or no change in the surrounding habitat as we own the land. It is my understanding this is a common problem throughout the bird's former range. Yes, there are problems with cowbirds, but the main reason for this decline has been the loss of wintering grounds in Central America. This was documented by Peter Vickery in a written article titled, "Requiem for the Wood Thrush." He also gave a lecture on his article at Maine Audubon, which I happened to attend. This is the same reason for the reduction in the populations of many Neotropical migrants. It made me see how interference of the USA (via the Monroe Doctrine) in Central and South America made this situation even worse. We protected American businesses in Latin America that were seriously damaging the environment.
