At the start of my day of birding, I stopped at Fourth Pond. It doesn't always yield birds, but when it does, they are often good ones. Last year, Catherine Barrett had a Ruff here. Every time I almost pass the road by, I think of that great find, and I am motivated to drive down to the pond.
I really looked this bird over and found it to be very small, even smaller than a Tree Swallow. Its tail was smaller and different from a Tree Swallow. Guessing, I concluded it was a Bank Swallow. I wouldn't dare take my eyes off of it to check my guide for fear that it might take off.
It began to squirm a bit and gave me a slightly different view. Had to be a Bank Swallow! I have never seen one, and I was pretty excited.
I haven't forgotten about the Tree Swallow, but plan to dedicate a post to it in the future. The good news is that a male Tree Swallow has been in my yard for the last three mornings straight....checking out my nesting box.
