The greater flamingo (Phoenicopterus roseus) is a wading bird of incomparable aspect due to its endless and slender legs, its long neck, the shape of its beak, and its pink coloring. The shape of its skeleton and the arrangement of its muscles recalls that of storks. The flamingo's muscles act as air sacs connected to its lungs and distributed throughout its body to provide a pneumatic effect that improves its support in flight and its buoyancy.
