Seasonal patterns of bird and bat collision fatalities at wind turbines
Author: Lloyd, John; Butryn, Ryan; Pearman-Gillman, Schuyler; and Allison, Taber
Abstract – Information on when birds and bats die from collisions with wind turbines can help refine efforts to minimize fatalities via curtailment of energy productions and can offer insight into the risk factors associated with collision fatalities. Using data pooled from 114 post-construction monitoring studies conducted at wind facilities across the United States, we described seasonal patterns of fatalities among birds and bats. Bat fatalities peaked in the fall. Silver-haired bat (Lasionycteris noctivagans), a long-distance migrant, and Mexican free-tailed bat . . .

Wind Energy’s Impact on Birds, Bats, and Insects
Author: McPherrin, Jack
Impact on Birds and Bats Substantial research has been conducted that links wind turbines to avian fatalities. The majority of birds that are impacted by wind turbines are birds of prey. Wind turbines create wind vortexes that draw in birds and cause fatal collisions with the turbine blades. Birds of prey and wind developers are both drawn to the same sites—hills, ridges, and other elevated areas—where stronger currents provide more stable power for wind turbines, while also providing a greater . . .

Interaction Between Resource Species and Electromagnetic Fields Associated with Electricity Production by Offshore Wind Farms
Author: Hutchison, Zoë; Secor, David; and Gill, Andrew
ABSTRACT. As offshore wind energy production increases, the number of subsea cables will proliferate along with associated electromagnetic field (EMF) emissions. Understanding how EMF interactions (a potential pressure) affect resource species (receptor) requires an improved knowledge base to aid management decisions. Within the framework of a potential effect on a receptor, we review key aspects of assessing EMF exposure. From the vantage point of the receptor species, we consider how their perception of EMF varies through time as a consequence . . .

The presence of wind turbines repels bats in boreal forests
Author: Gaultier, Simon; et al.
Highlights Presence of Eptesicus nilssonii and Myotis spp. are higher further from wind turbines located in forests. The avoidance of wind turbines or their surroundings could mean important loss of habitats for bats. Bat activity at wind power sites in forests varies with night length and season in the boreal zone. Mitigating this avoidance effect in current and future wind farms requires stronger regulations in Finland and the rest of Europe. Abstract Impacts of wind power on bats are usually . . .
