8 - 9 am, A lot of song from the nesters. Particularly active were Wood Thrushes, Towhees, White-eyed Vireos.  Most birds hard to see, but we got good visuals on a Yellow-billed Cuckoo, Prairie Warbler, and Rose-breasted Grosbeak.  For what it's worth, Merlin thought it heard an Acadian Flycatcher.
