Reproductive success of Potomac River ospreys--1970
Abstract
Osprey reproductive success on the Potomac River during 1970 is described. Thirty-five percent of the accessible active nests fledged young and only 0.70 young were fledged per active nest. Egg failure was the major cause of poor success. Reproduction was below that considered normal for a stable population.
