Raptors and Land-Based Wind Energy in the United States

Bald Eagle

Wind energy is a critical element of a sustainable energy future; however, like many other energy resources, its development can have negative impacts on wildlife, including many avian species. Impacts to birds can be either direct through collision with wind turbine blades, or indirect through habitat loss from displacement or land use change. The associated infrastructure may pose additional hazards such as collisions with vehicles and electrocution from overhead distribution lines (Drewitt and Langston 2006; Smith and Dwyer 2016).

Some species of raptors are more vulnerable to collisions due to their flight patterns, physiology, and behavior. Many raptor species rely significantly on soaring flight, which is dependent on air currents. Unfortunately, these same air currents are often suitable for wind energy development, leading to an increased risk of collisions with wind turbines (Barrios and Rodriguez 2004; Péron et al. 2017). Additionally, the vision of raptors is more suited for focusing on distant objects, potentially diminishing their awareness of closer obstacles in their immediate vicinity, especially during hunting (Martin 2011; May et al. 2020). Moreover, raptors tend to have delayed sexual maturation and long life spans with relatively low reproductive capacity, resulting in populations that are slow to recover from additive mortality (Beston et al. 2016).
