Brown-headed Cowbirds

Caught these three Brown-headed Cowbirds at Confluence Park, just as the sky had turned black and the first few raindrops were beginning to fall. They seem to often stretch their heads upwards like this, giving a slim look to the body. Cowbirds will lay their eggs in the nests of other birds and many of the latter will incubate the eggs as their own and then raise the young Cowbirds.
