Cave Swallow update
- Andrew Howe and I were at the Cave Swallow spot from about 4 until dusk. The bird did not return. At dusk, there were about 200 or more swallows still feeding to the west of Davis a little north of Pound, but no swallows had (yet) gone to roost along Pound. As the light was fading, the feeding flock vanished off to the northwest.
