What birds spend all their time on their knees?
Birds of prey!
Interesting Fact: The name “peregrine” means wanderer, and the Peregrine Falcon has one of the longest migrations of any North American bird. Tundra-nesting falcons winter in South America, and may move 25,000 km (15,500 mi) in a year. Maps of the migration of individual falcons determined by satellite telemetry can be seen at Environment Canada. ( http://www.allaboutbirds.org/guide/Peregrine_Falcon/lifehistory )
