WebThe highly pneumatic bones of large flying birds are reinforced with bony struts at points of stress. The humerus, radius, and ulna are well developed. The secondary flight feathers are attached to the ulna, which thus directly transmits force from the flight muscles to these feathers and is therefore relatively heavier than the radius. WebMar 25, 2024 · The keel, or breastbone, is extremely pronounced in most birds. Large and bladelike, it is a thin slab of bone along which the massive flight muscles are anchored. It also provides additional protection for the heart and lungs. Some flightless birds, specifically the ratites, have no use for a pronounced keel, and it is therefore absent.
