Wednesday Wings - Brown-headed Cowbird
The Brown-headed Cowbirds are obnoxious in so many ways. They're strongly built, aggressive, and dominate all the smaller, gentler songbirds.
They don't bother to build a nest. Instead, they lay their eggs in the nest of any bird they can dominate. The host bird unknowing hatches the Cowbird egg(s) and raises the Cowbird chick(s).
The hatchling Cowbirds are large, demanding, and rude. They take over the nest getting most of the food. The unwitting host's hatchlings go hungry, sometimes to the point of death.
Even at the feeding board, this Cardinal knows it wants nothing to do with this horrid female Cowbird.
Yesterday there were three female Cowbirds at the feeder. Each one has two to three dozen eggs a summer to deposit in an unsuspecting nice bird's nest.
This picture was taken at the end of nesting season last summer.
The young Cowbird is still harassing its adoptive parents, a male and female Rose-breasted Grosbeak. It wants to be fed. NOW!!!! And again and again.
Mr. and Mrs. Rosy are trying hard to make the demanding Cowbird happy, but it's impossible.
This picture was also taken at the end of nesting season last summer.
