fresc.usgs.gov — Ferruginous Hawks (Buteo regalis) studies are being conducted to evaluate the efficacy of monitoring long-term trends of the Ferruginous Hawk (Buteo regalis) nesting and productivity. The basic approach involves comparing estimates of occupancy and productivity based on surveys of historical territories with estimates from quadrant sampling.
