Bad Birds

I'm on the hunt for a redeeming quality in the brown-headed cowbird.  They hog my feeder.  They have an ugly name.   They aren't particularly attractive.  They have an annoying trill as a call.  And, worst of all...they are brood parasites who steal eggs from other nests and replace them with their own so that the surrogate parent bird will feed and care for their young.
