Last Sunday, I attended a South Shore Bird Club outing in Fairhaven, MA led by Jim Sweeney. Our small group of seven birders visited several coastal locations and observed a variety of species. Highlights included a Merlin, American Oystercatchers, Black, Common and Least Terns, and a few Saltmarsh Sparrows.
But the most awe-inspiring sight of the morning was the flock of Tree Swallows we observed from West Island Beach. We estimated roughly 1,000 Tree Swallows! I'd been wondering where the inland Tree Swallows had gone -- it seems at least some of them have flocked up along the south coast of Massachusetts. The following photos attempt to convey the jaw-dropping density of swallows.
