North Acton Marathon

Three hours of birding this morning, mostly at the tennis bubble and NARA.

Besides the forest full of yellow rumps and palm warblers, there were a lot of Warbling Vireos making a racket at the top of the trees.

I also so two birds I don't see very often.

An Eastern Towhee 

and a Killdeer.

Also seen was my first hummingbird of the year and a Red Bellied Woodpecker.
