As is true for any structure shaped by natural selection, bird anatomy has evolved to fit a particular species' behavior and lifestyle.

Bird anatomy is primarily adapted for efficient flight.

Despite some errors in field observations, he made a significant contribution to the understanding of bird anatomy and behavior through his field notes.

Bird banding helps biologists understand migratory habits and bird anatomy.

Bird anatomy, or the physiological structure of birds' bodies, shows many unique adaptations, mostly aiding flight.

Evidence from modern bird anatomy, fossils and DNA have all been brought to bear on the problem but no strong consensus has emerged.

Additional drawings depict nests, feathers, and details of bird anatomy including feet, breastbones, and windpipes.

JC Harrison was a keen supporter of Norfolk Wildlife Trust and practised taxidermy in order to improve his knowledge of bird anatomy.

In 2007, a far more comprehensive cladistic analysis of bird anatomy including some fossil forms (though not the crucial Late Cretaceous taxa, which are usually known only from fragmentary remains) resolved the "higher waterbird" radiation somewhat better; still, the problem of leg and foot traits confounding the analysis was noticeable.
