Osprey

Pandion haliaetus ORDER: ACCIPITRIFORMES FAMILY: PANDIONIDAE

IUCN Conservation Status: Least Concern

Unique among North American raptors for its diet of live fish and ability to dive into water to catch them, Ospreys are common sights soaring over shorelines, patrolling waterways, and standing on their huge stick nests, white heads gleaming. These large, rangy hawks do well around humans and have rebounded in numbers following the ban on the pesticide DDT. Hunting Ospreys are a picture of concentration, diving with feet outstretched and yellow eyes sighting straight along their talons.

Calls

Ospreys have high-pitched, whistling voices. Their calls can be given as a slow succession of chirps during flight or as an alarm call—or strung together into a series that rises in intensity and then falls away, similar to the sound of a whistling kettle taken rapidly off a stove. This second type of call is most often given as an unfamiliar Osprey approaches the nest. As the perceived threat increases, the call can build in intensity to a wavering squeal.

Find This Bird

Near open water with an abundant supply of fish, listen for the Osprey’s whistling or chirping calls overhead, or look for this bird's distinctive flight profile and heavy wingbeats. From spring into fall, a boat or raft on a lake or river can provide an especially good vantage point. Scan treetops and other high spots along the shore for perched adults and untidy stick nests piled atop a platform, pole, or snag out in the open.
