We don't see Brown-headed Cowbirds in our yard during most of the year, but every spring a pair show up and use our feeders, looking for nests to paratisitize -- successfully, see below.
The cowbirds make good use of our feeders, and in Spring 2008 I photographed a Dark-eyed Junco adult feeding a cowbird chick at one of them.
