That's true, but I wouldn't care too much about the hunting aspect of being a peregrine falcon. I'd be too busy focusing on flying at very high speeds!
Actually, it only has the largest wingspan of any living bird. The ostrich is the largest living bird, the argentavis is the largest flying bird ever, and the elephant bird is the heaviest ever.
There's also one called the magmusavis that's said to have been pretty large, but I couldn't find a Wikipedia article on it! =P
i'd be a squirrel just cause they jump/climb on trees and store nuts. but then you have hunters coming for you and any other animals. squirrels are so cute xD
