Birds have a furcula which is a bone located in the bird's chest that prevents compression of the chest cavity during the downstroke of a wingbeat.
ReplyDeleteSome birds have hollow bone structure to reduce weight during flight.
ReplyDeleteFalcons, when gone through about half of its life, its feathers get old. They can either keep it that way or they can go through a process called reborn, which allows it to tear its own feathers with its beak and after a few months, new feathers grow in its place.
