After examining photos and getting consultation, the Empid the NTOS group
had at the Radnor spillway was not an Acadian, but rather a first of
season LEAST FLYCATCHER. Way to shake off the post-winter rust. I knew
something wasn't right about it, but with 30+ people on the bridge trying
to get eyes on it, I think it was too hectic for critical thinking.
Thanks Hugh Barger and Jackie Corbin for raising the flag before I got
around to double checking - and thanks Mike Todd for lending more
experienced eyes to it.
Updated ebird list below with photos.
