To assess the effects of rotenone (fish toxicant) treatment and possible fish removal effects on nesting Osprey (Pandion haliaetus) populations, nests were observed at two reservoirs east of Ashland, Oregon. Hyatt Reservoir was treated with rotenone on October 12, 1989. Howard Prairie was observed as an untreated reference area. Nests at both reservoirs were observed two years pre-treatment (1988, 1989) and two years post-treatment (1990, 1992). The dataset contains Osprey reproductive parameters, foraging parameters, prey delivery rates and bald eagle piracy rates at eight intensively observed nests. Fish stocking records and creel data were obtained from the Oregon Department of Fish & Wildlife for both reservoirs...

A small numbers of Ospreys (Pandion haliaetus) are known to have nested historically in Utah. A precise baseline figure is unavailable, but the 19th-century Osprey population in Utah probably consisted of at least 15 breeding pairs scattered in 4 geographic regions. Human persecution is believed to have caused the abandonment of nesting territories along the Wasatch Front and in the western Uinta Mountains by 1900 and 1960, respectively. Osprey populations in the southern plateaus and Green River areas, however, began increasing in the late 1970s. Several recent nesting attempts and numerous summer sightings at nontraditional and abandoned historical sites in Utah suggest the Osprey is also expanding its range in...
