Humming birds usually show similar features in size and flapping wing kinematics compared with insects but discrepancy in aerodynamic performance. In this study, we construct a realistic morphological and kinematic model of rufous hummingbird (Selasphorus rufus) for the computational fluid dynamic (CFD) study of hovering aerodynamics. We present results of the near-and far-field vortex flow structures around the animal in hovering, and further discuss about their relationship with the lift generation mechanisms.
