STEVE INSKEEP, HOST:
Good morning. I'm Steve Inskeep with news of the magpie. It's a colorful little bird that weighs just a few ounces and will attack you like a beast if it perceives you as a threat. An 8-year-old in Australia saw a magpie swoop down on somebody and wondered just who they target. She conducted a study. Thirty thousand people participated, and she found magpies attack men with thin or receding hair. Nobody had made this connection before. Now researchers are combing through her data.
