Thanks for this information maeve.
Yesterday while in the swamp (which are vary dry.)picking blueberries I heard a bird singing which I have never heard before. Try as I may to see it I was not successful. However, next time I will bring my binoculars just in case. Question, anyone have a good web site that I can browse to listen to bird songs? I'm sure I will recognize it if I hear it again.
