“It’s early June – I bet that’s a female with a brood patch.”
Indeed it was.
Today marked the first casualty of a species that is common and conspicuous on campus – a House Finch at the southwestern alcove. As seems to be the case with resident birds, June is evidently a time for post-breeding dispersal, and this bird was, like many June casualties before her, a female with a brood patch.
I left her in place for a removal trial.
