A Red Knot smiles for the camera. The serrations on the inside of its bill help it grip slippery things. They look like the "teeth" on a saw, but they're not real teeth, so the Red Knot never has to go to the dentist!

In a July 29, 2011 photo, Pee Wee, a Barbary falcon, gets to eat after chasing away some starlings at Sakuma Brothers Farms' blueberry field in Burlington, Wash. Recently, Pee Wee decided to quit his job (halfway through a shift) and fly away to less blueberry-filled pastures.
