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.
The skeleton of a bird wing. Places of attachment of various groups of flight feathers are indicated. The mute swan with outstretched wings Wing of the white-tailed eagle. Bird wings are a paired forelimb in birds. The wings give the birds the ability to fly, creating lift. Terrestrial flightless birds have reduced wings or none at all (for ...
In economics, a Swan Diagram, also known as the Australian model (because it was originally published by Australian economist Trevor Swan [1] in 1956 to model the Australian economy during the Great Depression), represents the situation of a country with a currency peg.
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] In birds, its primary function is in the strengthening of the thoracic skeleton to withstand the rigors of flight.
This stylised bird skeleton highlights the uncinate processes. The uncinate processes of the ribs are extensions of bone that project caudally from the vertical segment of each rib. (Uncinate means hooked from Latin uncinatus, from uncinus, barb, from uncus, hook.)
Pigeon skeleton with "plowshare"-type pygostyle (number 17) Confuciusornis sanctus with "rod"-type pygostyle and the two central tail feathers Pygostyle describes a skeletal condition in which the final few caudal vertebrae are fused into a single ossification , supporting the tail feathers and musculature.
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.
