Seasonal movements of the short-eared owl (asio flammeus) in western north america as revealed by satellite telemetry. Johnson, J. A, Booms, T. L, Decicco, L. H, & Douglas, D. C Journal of Raptor Research, 51(2):115–128, 2017. Publisher: Raptor Research Foundation, IncPaper doi abstract bibtex The Short-eared Owl (Asio flammeus) is a widespread raptor whose abundance and distribution fluctuates in response to the varying amplitudes of its prey, which are predominately microtines. Previous efforts to describe the seasonal movements of Short-eared Owls have been hindered by few band recoveries and the species' cryptic and irruptive behavior. We attached satellite transmitters to adult Short-eared Owls at breeding areas in western and interior Alaska in June 2009 and July 2010, and tracked their movements for up to 19 mo. Owls initiated long-distance southward movements from Alaska and most followed a corridor east of the Rocky Mountains into the Prairie provinces and Great Plains states. Four owls followed a coastal route west of the Rocky Mountains, including one owl that crossed the Gulf of Alaska. Completed autumn migration distances ranged from 3205-6886 km (mean ¼ 4722 6 1156 km [SD]). Wintering areas spanned 218 of latitude from central Montana to southern Texas, and 248 of longitude from central California to western Kansas. Subsequent seasonal migrations were generally northward in spring and southward in autumn; these movements were comparatively short-distance (mean ¼ 767.5 6 517.4 km [SD]) and the owls exhibited low site fidelity. The Short-eared Owls we tracked from two relatively local breeding areas in Alaska used a patchwork of diverse open habitats across a large area of North America, which highlights that effective conservation of this species requires a collaborative, continental-scale focus.
