Brown-headed Cowbirds which are well-known as brood parasites. (They lay their eggs in the nests of birds of other
species and get the other birds to feed and raise their young)
Science Daily Reported on new research that reveals contrary to the behaviors of most female birds, Brown-headed Cowbird females choose maleswith what might be considered less impressive displays. UC Santa Barbara researchers
used audiovisual recordings of male cowbirds displaying for females. They discovered that the “less intense the wing spreading, feather puffing, and bowing were during a display, the more sexually interested the female would be.” It was also observed that females prefered older males possibly because they had better quality genes that allowed them to survive longer. Findings were published May 2 in the open access journal PLoS ONE.
