Episode description
Birds like male turkeys or barnyard roosters have a wrinkly, bumpy flap of red skin called a wattle. But what are wattles for? Birds can’t sweat, so wattles help release excess heat. Wattles are also key to courtship displays. Many other birds, including some storks and plovers, also have wattles.
