This information might have been posted somewhere already,
I just got my copy of Audobon magazine, "Birds in focus" awards issue.
I recognized two of the names as members of BPN:
Robert Amoruso 3rd award professional
and
Aidan Briggs, 1st award youth.
Hard to see the Yellow-headed Blackbirds in the magazine and even in this JPG. But in hi-res they are visible and I confirmed their presence in other images of the same group at faster shutter speeds.
