The present study aims at developing a 3-D trajectory measurement system for birds, in particular for endangered species, e.g. raptorial, flying around wind turbines as a part of its complete system to be applied for prevention from bird strike. The method is based on stereoscopic photography, which is similar to 3-D particle tracking velocimetry. For stabilizing the bird-image detection performance in natural background, the time differential technique is proposed and examined considering constraint of time of day and weather on the measurement. All tests are conducted in outdoor farm. For the demonstration purpose, 3-D trajectories of crows flying above the farm are obtained and shown in order to assess the effectiveness of stereoscopic photography for live birds.
