<p>The tail augments the primary purpose of the wings by contributing to the static stability of the flapping wing micro aerial vehicles (FWMAVs) and providing maneuverability during the flight. The diversity and variation in the avian tail morphology have inspired its optimised adaptation in FWMAVs over the decades. Despite the abundance of natural varieties, several artificial tails are customised to satisfy distinct operational capabilities. The study examines the aerodynamic performance and post-fluid interaction effects of 5 different tail configurations adopted for FWMAVs. Necessary tail sizing calculations have been performed to execute parametric studies across the tail configurations with the same surface areas. This study evaluates the aerodynamic characteristics of both, natural and artificial tail configurations— delta, forked, rounded fan, conventional, and V-tail, by analysing flow separation, pressure–velocity contours, and control and drag forces. Through these computational simulations, we evaluate their performance, and highlight key observations on the axis of symmetry and surface area distribution. The study, through its novel investigations, highlights the possible implementations of the selected tail geometries for distinct operational requirements with given characteristics in FWMAVs.</p>
