The Brown-Headed Cowbird is often considered an unsavory character of the bird feeder crowd. Perceived like a seedy, back-alley character from a gangster film, many bird watchers chase the Cowbird away from their feeders. They see the Brown-Headed Cowbird as only a nuisance, taking food from the “pretty” birds. In many ways that could easily be a metaphor for human nature and life, but we won’t dwell on the greater philosophy and psychology behind it.
Brown-Headed Cowbirds are in many ways the loners of the bird world. But this loneliness is self-inflicted. The Brown-Headed Cowbird does not build a nest in which to lay eggs. Instead, the female leaves her grayish-white eggs with brown speckles in the nests of other birds. They are the only parasitic bird to reside in New Jersey. Their eggs have been found in the nests of over 200 different species. Some of these birds recognize an imposer and abandon the nest or remove the Cowbird egg. However, many other species raise the Brown-Headed Cowbirds’ babies along with their own young. It is this leaving of their young, like orphans, to fend for themselves in an ugly duckling situation that leads me to pity them.
But while this behavior may seem appalling to some bird lovers, especially those of us particularly partial to songbirds, we need to remember that such is the nature of nature. Brown-Headed Cowbirds were probably laying their eggs in the nests of other species long before man, pencil and paper in hand, decided to study and record his behavior. We shouldn’t judge them harshly for it.
