The Brown-headed Cowbird is a Brood Parasite (allaboutbirds.org). The female Cowbird will lay their eggs in nests of other species. Although some species are able to identify the different egg in their clutch most are forced to raise their foster child. Which really shows how strong instinct is, because how does a cow bird know how to be a cowbird if it’s not learning from it’s real parents?
The males are quite handsome with their brown head heads and iridescent black feathers shimmering purple tones (above). The female is more subdued with brown tones (below). [click on any picture to see larger image]
