[EBB Sightings] Potential breeding warblers in the East Bay (short)

I certainly understand the caution of our hardworking documentarians re: the breeding birds of Contra Costa CO. 

However! Bird demographics change all the time, albiet slowly (or perhaps with our quickening climate changes, not so slowly). 

Judi Sierra is a sober and serious observer of birds. She has been doing this for a long time, and is not in the least bit "flighty" (if you'll pardon the unintended pun) about her reporting. When quizzed privately about what led her to believe that it was indeed a fledge that she saw, she convinced me with the abundance of detail, both behavioral and morphological. This was not an injured adult, but a typical stupid clumsy fledge, a developmental stage that we have all seen and recognized in our various field excursions.

As I learned back in those long ago college Physics classes....change is the only constant. What's hard is our human adaptation to it.

I'm throwing my lot in with Judi's sighting as noted; a Townsend's Warbler fledgling was observed in the East Bay.
