摘要

Offshore wind facilities during both construction and operation may impact bird populations directly through mortality from collisions and indirectly through displacement that affects population fitness. We present data on population size, conservation importance, and ecological traits of bird species found in the vicinity of the Atlantic Outer Continental Shelf and a method of ranking their relative sensitivity to the impacts of collision and displacement. Based on both our literature synthesis and the collision sensitivity rank, avoidance behavior and flight height appear to be key factors that influence vulnerability to collision. More data are needed for both of these behavioral traits. The collision sensitivity rank identified that populations of gulls, phalaropes, cormorants, and jaegers are of particularly high concern on the Atlantic Outer Continental Shelf. Available literature and the displacement sensitivity rank both suggest that avoidance of wind facilities and habitat flexibility appear to be key behavioral traits causing potential loss of population fitness through displacement. The displacement sensitivity rank identified that populations of sea ducks, loons, and some alcid species are most vulnerable. The impacts of displacement on populations will be less immediate and less obvious than those of mortality from collision; therefore, we hope that the approach developed here for the Bureau of Ocean Energy Management will help prioritize monitoring programs of vulnerable species before, during, and after construction and assist with informing siting decisions for offshore wind facilities.
