This stylised bird skeleton highlights the synsacrum Pelvis of a Gull; formed by the Synsacrum (fused vertebrae placed centrally) and the two innominate bones either side. 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 ...
Bird anatomy, or the physiological structure of birds' bodies, shows many unique adaptations, mostly aiding flight.Birds have a light skeletal system and light but powerful musculature which, along with circulatory and respiratory systems capable of very high metabolic rates and oxygen supply, permit the bird to fly.

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
The anatomy of bird legs and feet is diverse, encompassing many accommodations to perform a wide variety of functions. [ 1 ] Most birds are classified as digitigrade animals, meaning they walk on their toes rather than the entire foot.
The bones of three fingers are preserved in the bird wing. The question of which fingers they are has been discussed for about 150 years, and an extensive literature is devoted to it. [ 2 ] [ 3 ] The anatomical, paleontological, and molecular data suggests that these are fingers 1–3, but embryological data suggests that these are actually ...
The fossil skeleton of a newly discovered dinosaur species was found in a position suggesting it slept like modern birds. Dinosaur from newfound species died in a pose that sheds light on ...
Surface projections of the major organs of the trunk, using the vertebral column and rib cage as main reference points of surface anatomy. Surface anatomy (also called superficial anatomy and visual anatomy) is the study of the external features of the body of an animal. [1] In birds, this is termed topography.
