Abstract

Nesting efforts of ospreys were studied in northeastern California. Major cases of nesting were high winds and eggshell breakage, but human disturbance was responsible for 33% of observed egg losses. In one case campers caused adult ospreys to abandon a nest with eggs. During fledgling counts young ospreys sometimes flew from nests, apparently for the first time. Such early flights may increase the incidence of injury and predation of fledglings.
