From above it looked pretty identical to a Golden-winged and would be easy to overlook if you didn't see the face.
The Blue-winged pattern comes out while looking up at it.
I doubt there's many Brewster's flight shots out there.
Surprisingly I've seen 3 or 4 Lawrence's (most recently last year at Chikaming), the F2 backcross between Brewster's and one of the parents, but never the F1 hybrid.
I went back to Floral in the afternoon, there were a ton of silent Ovenbirds.
It's been a really good spring for Orange-crowned, this one was from Tiscornia.
Finally a couple shots of spring migrants with the Marsh Marigolds that are currently in peak bloom.
