High vulnerability of juvenile Nathusius’ pipistrelle bats (Pipistrellus nathusii) at wind turbines
[abstract] Large numbers of bats are killed by wind turbines globally, yet the specific demographic consequences of wind turbine mortality are still unclear. In this study, we compared characteristics of Nathusius’ pipistrelles (Pipistrellus nathusii) killed at wind turbines (N = 119) to those observed within the live population (N = 524) during the summer migration period in Germany. We used generalised linear mixed effects modelling to identify demographic groups most vulnerable to wind turbine mortality, including sex, age (adult or . . . Complete article »

Bats and offshore wind turbines studied in southern Scandinavia
Summary A pilot study 2002-2003 at turbines on land showed that certain locations in the landscape could explain some of the casualty risks and the main reasons for collisions were found. During the 2005 introductory studies and in the project 2006 on bats in offshore areas in Kalmarsund we could confirm earlier known flyways from coastal points and found an extensive activity of passing migrants but also of resident species coming from various directions to areas with an abundance of . . .

Eurobats guidelines for consideration of bats in wind farm projects
Content sections include “General aspects of the planning process”, Carrying out impact assessments”, “Monitoring the impacts”, and “Research priorities”. Two tables outline the results of studies done in Europe and bats’ behavior in relation to wind facilities. Wind turbines “can have negative impacts on bat populations as well as on their prey and habitats, such as: • Damage, disturbance or destruction of foraging habitats and commuting corridors; • Damage, disturbance or destruction of roosts; • Increased collision risk for bats . . .
