Abstract
Knowledge about the morphological adaptations of body and wing in birds
helps to know about their aerodynamic performance. The present study was
aimed to analyze the morphometry of the wing of the blue and yellow
macaw (Ara ararauna) with reference to aerodynamics. Various
aerodynamic measurements namely body weight, body length, wing span,
wing area, wing load and aspect ratio were measured in three adult male
birds. The wings were short, elliptical and rounded. The mean value of
body weight, body length, wing length, wing span, wing area, wing load
and aspect ratio of the blue and yellow macaw were 1080 ± 95.34 g, 174.46
± 4.87 cm, 34.67 ± 4.87 cm, 77.4 ± 3.67 cm, 1294 ± 54.32 cm2, 0.834 ±
0.01cm-2 and 4.626 ± 0.57 respectively. The low aspect ratio suggested
ability to maneuver tightly in confined spaces like dense vegetation. All
anatomical and aerodynamical measurements concluded that blue-and yellow
macaw was adapted to flapping flight
