Birds of a Feather
3/9/14 and 3/10/14: This week on "Fieldnotes:" "Bird Social Behavior," by Mark Hanson.
"Except when mating and nesting, Bohemian and Cedar waxwings are simply highly social birds. They seek food and water supplies large enough for the entire flock. Even more remarkably, they will sometimes pass berries from bird to bird down a line until a berry is finally swallowed. They not only eat together, but they may also become intoxicated together, indulging their tendency to gorge themselves on overripe berries."
