It's been pretty steamy in Boston, and the birds are feeling it too. On my trip to Mt. Auburn Cemetery three weeks ago I also stopped to watch a Double-crested Cormorant cooling in Auburn Lake.
These pictures were not taken at a fast shutter speed- the bird was simply holding its wings up and fanning them very, very slowly.
It was such a hot day, and this was such a small, sheltered body of water it made me wonder why it wasn't out in the open ocean or even in the Charles River where I see lots of them. It's a mystery. Has anyone else spotted cormorants in small ponds like this before?
