Osprey

The Osprey is a large, distinctive raptor found near water on every continent except Antarctica, and is the only member of its family. Highly specialized for catching fish, it has clean white underparts and head, a bold dark stripe through the eye, and a dark brown back, giving it a strikingly contrasted appearance both perched and in flight.

In flight, the wings are held with a distinctive bend at the wrist, giving a gull-like, slightly kinked silhouette that is often the quickest way to identify an Osprey at a distance.

Key field marks

• Clean white head and underparts with a bold dark eye-stripe
• Dark brown back and upperwings
• Long wings held with a distinctive crook or bend at the wrist in flight
• Dark carpal patches visible on the underwing

Similar species

Bald Eagle (immature) can show extensive white but has a much larger, heavier build, a solid dark eye area rather than a crisp stripe, and flat (not kinked) wings in flight. No other North American raptor combines the Osprey's clean white underparts with its gull-like, bent-wing flight silhouette.

Habitat

Found near virtually any body of water with abundant fish and suitable nest sites: lakes, rivers, reservoirs, marshes, and coastal bays and estuaries.

Range

One of the most widely distributed raptors in the world. In North America, breeds across much of Canada and the United States, particularly near coasts, lakes, and rivers. Most North American Ospreys are long-distance migrants, wintering in Central and South America, with a smaller number remaining year-round in the mildest parts of their range, such as Florida.

Behavior

Ospreys hunt by hovering or circling over water and then plunging feet-first, sometimes fully submerging, to seize fish near the surface with sharply curved talons. A reversible outer toe and spiny footpads help them grip slippery prey securely, and they typically carry fish head-forward to reduce wind resistance in flight.

Voice

Gives a series of high, clear, whistled notes, often a repeated "cheep-cheep-cheep," especially around the nest.

Feeding and nesting

Diet is almost exclusively live fish, caught in dramatic dives. Builds a large stick nest, often on top of dead trees, channel markers, utility poles, or purpose-built nesting platforms, frequently reused and expanded across many breeding seasons.
