Bird populations in Maine are continually changing. Bald Eagles and Wild Turkeys were nearly gone from Maine in the 1900s, but have returned. On the other hand, numbers of American Kestrel, Tree Swallow, and Evening Grosbeak are all down. What are the causes of these shifting numbers? This presentation covers the last few decades and discusses which species are disappearing, which are increasing, and then looks into the future to identify what the future of Maine birds might be.
