Cowbird Mafia
Manage episode 439836216 series 2973238
Brown-headed Cowbirds have a sneaky approach to parenthood. They lay eggs in the nests of other songbirds, and the songbird hosts often raise the cowbird chick as their own. It’s called nest parasitism. But sometimes the hosts throw out the odd-looking egg. And when that happens, the cowbirds sometimes retaliate by destroying the hosts’ other eggs. Scientists call this “mafia behavior,” likening it to organized crime groups enforcing their demands on unwilling business partners.
