Ospreys Courting & Copulating

Ospreys have returned to their breeding grounds in New England, where both courtship and copulation is taking place.  The males engage in an undulating courtship display flight high over the nest site, often with fish or nesting material clutched in their dangling legs while they repeatedly issue forth screaming calls.  This can go on for up to ten minutes or so before they descend to the nest.  In addition, “courtship feeding” often takes place with the male providing his mate with food, often just prior to breeding.

Although an osprey pair copulates frequently (an average of 160 times per clutch), nearly half the time there is no cloacal contact. Most of the breeding takes place at or near the nest site. (Note the protective positioning of the male’s toes and talons as he mounts his mate.)
