This collaborative project will result in the first fine-scale quantitative assessment of the migratory period for regional priority grassland songbirds (Spragues Pipit, Chestnut-collared and McCowns Longspurs, Bairds and Grasshopper Sparrows, and Lark Bunting). Data collected via automated telemetry tracking will inform full-life cycle models to reveal limiting factors and identify critical habitat for these species throughout the annual cycle, particularly migration.
