Bosakowski and Speiser Habitat Requirements: Cover: Goshawks nest in interiors of extensive, remote, mature and old-growth forests dominated by large trees, high canopy closure, on moderate slope, with an open understory (Falk 1990, Speiser and Bosakowski 1987, Squires and Reynolds 1997). from human disturbance. Bosakowski, T. and D.G. old-growth forests dominated by large trees, high canopy closure, on moderate We While pursuing prey, Northern goshawks have been described both “reckless” and “fearless” as they are able to pursue their prey through nearly any conditions.
