CONT

Various factors contribute to wind turbine induced bird mortality, such as the wind turbine design and arrangement, bird species, and climatic variables. ... The bird mortality rate increased in areas where turbines are located on ridges, on upwind slopes, or close to the bird migration routes. For example, if a wind farm is on a bird migratory route, birds have to avoid the wind farm and deviate from their usual route. The extra deviation work will increase the energy expenditure of the birds and reduce their survival rates. This wind farm barrier effect on birds is species-specific.
