Study of White-Tailed Eagle Haliaeetus albicilla movements and mortality at a wind farm in Norway
Author: Nygård, Torgeir; et al.
The wind power plant on the island of Smøla, western Norway, is currently the largest in Norway; it has 68 turbines with nominal capacity of 2–2.3 MW each, hub height of 70 m and rotor blade radius of 38–41 m. It was constructed in two phases between 2001 and 2005. Approximately 60 White-tailed Eagle Haliaeetus albicilla territories are found in the whole Smøla archipelago. Before construction there were 13 Eagle pairs holding territories in the wind farm area and within 500 m of . . .

Author: Lie Dahl, Espen; May, Roel; et al.
ABSTRACT: Evidence is increasing of bird mortality due to large-scale wind-energy development. Soaring raptors, such as the white-tailed eagle (Haliaeetus albicilla), have proven particularly vulnerable to collisions. In this study, we compared white-tailed eagle flight behavior both inside and outside of the Smøla wind- power plant on coastal Central Norway. During the eagle breeding period (mid-Mar–end May 2008), we collected data on flight activity (directional flight, social behavior, and soaring) and flight altitude (below, within, and above the rotor-swept zone . . .

Author: Krone, Oliver; and Treu, Gabriele
ABSTRACT: White-tailed sea eagles (Haliaeetus albicilla) exhibit one of the highest mortality rates at wind power plants (WPPs) among raptor species in Europe, but data on circumstances of collision and behavioral response to WPPs are scarce. We analyzed the effect of WPPs on movement patterns of sea eagles in Germany with satellite telemetry. We analyzed ranging behavior and environmental parameters that influence the behavioral flight response to WPPs using multiple regression models. During 2003 through 2009 we radio-tracked 25 white-tailed . . .

Author: Lie Dahl, Espen; et al.
Abstract— Climate change scenarios and efforts to reduce CO₂ emissions have increased the focus on wind power and other renewable energy sources. Despite producing “clean” electricity, windfarms do have impacts on the environment. We studied the impact from a coastal windfarm on the breeding success of white-tailed eagles (Haliaeetus albicilla) at Smøla, western Norway by means of a BACI (before–after–control–impact) approach. The objective was to compare pre- and post-construction breeding success. A 10 year dataset from 47 eagle territories was . . .
