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 flighten-USVeterinary ScienceVeterinary AnatomyArticle
