| Abstract: | The status of ospreys (Pandion haliaetus carolinensis) in seven states, as determined by comparison of recently observed rates of production to rates required to maintain a stable population, is discussed. It is estimated that 1.22-1.30 young must be produced per active nest (including unsuccesful nests) to maintain a stable population. The decline in numbers of ospreys was not uniform throughout the United States. The population at Florida Bay, Florida, seemed to be stable as opposed to the estimated 12-14 percent (minimal) annual decline in numbers during the 1960s of localized populations in Connecticut, Maine, Michigan, and Wisconsin. For the same time period, populations in Maryland and Minnesota were estimated to be declining at a 2-3 percent rate annually. |
