An estimated 308 ? 23 pairs of Ospreys nested in the survey area in Oregon in 1976. Major concentration centers include Crane Prairie Reservoir and the adjacent Deschutes National Forest, the coastal lakes and reservoirs between Florence and North Bend, the Rogue River, the Lane County reservoirs, and the Umpqua River. An estimated 47 percent of the Oregon population is nesting at reservoirs. Limited information is available concerning the long-term status of the Oregon population; however, the ability of the species to pioneer newly created reservoirs emphasizes that the population is utilizing new habitats.
