Bioacoustic Monitoring Reveals Patterns of Landscape Use by Migrating Birds at a Great Lakes Barrier Crossing.

ABSTRACT: Understanding how highly mobile animals use landscapes at broad geographic scales remains a major challenge in ecology. Traditional monitoring approaches often lack the spatial and temporal resolution to monitor how migratory species use heterogeneous landscapes, contend with movement barriers, and interact with urban and developed landscapes. Here, we use a passive acoustic monitoring network to characterize landscape use of migrating songbirds in the Keweenaw peninsula, a major barrier crossing point along the south shore of Lake Superior. Using nearly 3 million acoustic detections of migrants from 18 sites spanning 328 km², we demonstrate that landscape use is shaped strongly by local geography and wind conditions during reoriented movements associated with barrier crossing.
