The bird skeleton is highly adapted for flight. It is extremely lightweight but strong enough to withstand the stresses of taking off, flying, and landing. One key adaptation is the fusing of bones into single ossifications, such as the pygostyle. Because of this, birds usually have a smaller number of bones than other terrestrial vertebrates.
This stylised bird skeleton highlights the furcula Wishbone of a chicken. The furcula (Latin for "little fork"; pl.: furculae) [a] or wishbone is a forked bone found in most birds and some species of non-avian dinosaurs, and is formed by the fusion of the two clavicles. [1]
The structure of the fossils also suggest that these birds may have been swifter than originally thought. [25] A skull from a smaller subspecies of this bird was also found recently. With this fossil, it was found that the internal structure of the beak is hollow and reinforced with thin-walled trabeculae.
Birds are a group of warm-blooded vertebrates constituting the class Aves (Latin:), characterised by feathers, toothless beaked jaws, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart, and a strong yet lightweight skeleton. Birds live worldwide and range in size from the 5.5 cm (2.2 in) bee hummingbird to the 2.8 m ...
This stylised bird skeleton highlights the synsacrum Synsacrum of an unidentified bird. The synsacrum is a skeletal structure of birds and other dinosaurs, in which the sacrum is extended by incorporation of additional fused or partially fused caudal or lumbar vertebrae. This structure can only be seen in birds.
This stylised bird skeleton highlights the keel bone. A keel or carina (pl.: carinae) in bird anatomy is an extension of the sternum (breastbone) which runs axially along the midline of the sternum and extends outward, perpendicular to the plane of the ribs.

Pigeon skeleton. Number 8 indicates both left and right tarsometatarsus. The tarsometatarsus is a bone that is only found in the lower leg of birds and some non-avian dinosaurs. . It is formed from the fusion of several bones found in other types of animals, and homologous to the mammalian tarsus (ankle bones) and metatarsal bones (foo
