Jargon-free and easily accessible to any reader, the lively text relates birds' anatomy to their lifestyle and evolution, examining such questions as why penguins are bigger than auks, whether harrier hawks really have double-jointed legs, and the difference between wing claws and wing spurs. A...
Bird - Anatomy, Flight, Migration: The structures associated with flight distinguish birds from other animals. Feathers are made of keratin; contour feathers are shed and replaced (molted) at least once a year. Color is caused by pigments and structure.

The fossil record of birds in the Mesozoic of Gondwana is mostly based on isolated and often poorly preserved specimens, none of which has preserved details on feather anatomy. We provide the description of a fossil bird represented by a skeleton with fe

‘bumps’. So inArchaeopteryx, the primary and secondary wing feathers are attached to the ‘hand’ and ulna, respectively. And the feathers on the tail are actually minutely attached to each of the 20 vertebrae. There are also a lot of small feathers on the legs and body of this bird,...
Feathers do not have to be especially strong but they do need to be stiff and at the same time resilient and to have a high work of fracture. Syncitial barbule fibres are the highest size-class of continuous filaments in the cortex of the rachis of the feather. However, the rachis can...
