While sitting on the bench at the Butterfly Meadow, I could hear a house wren calling repeatedly nearby. Eventually I saw a couple of wrens a juvenile, as here, and an adult.

Bird activity was fairly quiet on this overcast, but humid, day. However, a really nice sight was of about a dozen barn swallows, mostly juveniles, swooping over the old field area. Don't see these swallows much around the garden anymore. And of course, American goldfinches were everywhere! I caught a glimpse of a flycatcher with a mouth full of food, but didn't see the bird well enough to ID it. It was in deep shade, but the white larvae in its bill stood out, however, it looked more like a pewee than anything, in that 2 second shadowy glance. I looked for it for some time, but no luck.
