Abstract Bird can switch between high maneuverability and high stability due to its ability to substantially morph
wings and tail. Tail as an auxiliary lift surface, plays an important role on lift and drag production and also
significantly affects the longitudinal stability. In this study, we reconstruct a high-fidelity barn owl model
using the point cloud of its surface obtained from high-speed photogrammetry, and simulate the fluid
dynamics using a commercial software. By virtually manipulating the tail to a series of postures, we analyze
the aerodynamics and static stability for each tail posture, investigating the strategy to adjust the stability
