This paper is focused on four bird’s airfoils namely Seagull, Merganser, Teal and Owl which are extracted from their respective wing cross-sections. In addition to this, the corrugation due to feather roughness of Swift bird is imposed on Seagull. The aerodynamic performance of these 4 avian airfoils and corrugated Seagull airfoil is tested in Reynolds number in the range of 104 – 105. Seagull and owl indicates better aerodynamic performance in 4 airfoils and analysed how the flow behaviour by tracking the laminar separation bubble. Seagull Corrugated illustrates better performance than seagull in small Reynolds number.
