Pdf Qualitative Skeletal Correlates Of Wing Shape In Extant Birds Background among living fliers (birds, bats, and insects), birds display relatively high aspect ratios, a dimensionless shape variable that distinguishes long and narrow vs. short and broad wings. increasing aspect ratio results in a functional tradeoff between low induced drag (efficient cruise) and increased wing inertia (difficult takeoff). given the wide scope of its functional effects.

Pdf Qualitative Skeletal Correlates Of Wing Shape In Extant Birds Qualitative skeletal correlates of wing shape in extant birds (aves: neoaves) bmc evolutionary biology united kingdom doi 10.1186 s12862 015 0303 7. A comparative approach is used to investigate the relationship between skeletal proxies of flight feather attachment and wing shape in basal ornithurine birds, finding that quill knobs are cited as skeletal correlates of flight performance in birds, but their relationship to wing shape is inconsistent among extant taxa. A comparative approach is used to investigate the relationship between skeletal proxies of flight feather attachment and wing shape in basal ornithurine birds, finding that correlates of distal primary feather attachment on the major digit show convergent responses to increasing aspect ratio. Confident inference of wing shape in basal ornithurine birds will require multiple lines of evidence, together with an understanding of clade specific evolutionary trends within the crown. s epmc4394594 qualitative skeletal correlates of wing shape in extant birds (aves: neoaves).

Conclusions: although quill knobs are cited as skeletal correlates of flight performance in birds, their relationship to wing shape is inconsistent among extant taxa, and may reflect diverging selection pressures acting on a conserved architecture.
