Great Bustard is one of the heaviest birds in the Western Palearctic, so aerodynamic effects are critically important for their distribution and conversation. To understand why do they need to find open areas during the resting and feeding time, aerodynamic features were discussed in this study. Mass of the Great Bustard and having proportionally small wings cause weak flight performance. In this work, those disadvantages were identified by aerodynamic approach and observation. Great Bustard tries to use the relative wind during the take-off to close these disadvantages. Also, turning performance which is affected by the same specifications with take-off performance can determine their behavior. As a result, aerodynamic factors may also play important role in their current status.
