I visited 721 Progress today about 1PM. A very interesting little spot! I did not hear the Mockingbird but I did see/hear the following: Chestnut sided warbler, Yellow warbler, Goldfinch, Tree swallow, Kingbird, Mourning dove, Starling, RW Blackbird, Ring-billed gull and Willow Flycatcher (Fitz-buew). Cheers Terry
