Abstract: 

This study examines the probability of bird collisions with turbine blades using a sound mathematical model. The model takes into account the number of blades, pitch angle, rotor diameter, rotation speed, bird size, etc. Despite the study, current avoidance rates are inadequate based on the data coming from survey sample data and estimated mortality rates. Unfortunately, this makes the study only useful for comparative purposes.

 

To determine the probability of a bird being hit by blades, three case studies were implemented. They were the Bewick Swans in Southern England, Golden Eagles in Western Scotland, and the Seabirds in Southern England.
