How long do Osprey chicks stay in the nest? Parent Osprey and 5-6 week-old chicks. The time she takes to complete a clutch depends on the number of eggs she lays, and a 4-egg clutch typically takes between 8 to 10 days to complete.
The female osprey lays one egg every other day after she starts laying eggs. Osprey eggs are cream to pinkish cinnamon spotted and blotched with reddish-brown.

The female sits on the nest, arranging the nesting material.Īrtificial platforms are becoming a common nesting site as prime Osprey nesting sites are converted to urban development. The male finds the nesting site and collects most of the nesting material by fly-by-plucking thin branches of trees. The same nest is reused every year, and additional material is added, resulting in huge nests of up to 11 feet deep and 5 feet in diameter.

Osprey nests grow inĭepth as they are reused every year. The male makes repeated screaming calls while gradually descending in an undulating fashion to the nest.Ģ. A nearby source of food is the only requirement.Īt the beginning of the breeding season, males perform an aerial “sky-dance,” sometimes called “fish-flight.” With dangling legs, often clasping a fish or nesting material in his talons, the male alternates periods of hovering with slow, shallow swoops as high as 600 feet or more above the nest site. Ospreys nest mostly in North America, along the coasts of New England, Florida, and other regions (see the breeding range map below). They will chase away other Ospreys that encroach on their nesting areas. Nesting Ospreys defend only the immediate area around their nest rather than a larger territory. Many people provide nesting platforms, which birds readily take. Ospreys now nest on channel markers, communication towers, and utility poles. Some ospreys have nested within 10 miles of a body of water.Īreas near water have become prime real estate reducing the number of available nesting sites. Good nesting sites are emerging dead or live trees or other structures with easy access located near rivers, lakes, bays, reservoirs, lagoons, swamps, and marshes.
Ospreys nest in a wide variety of habitat types. Where do Ospreys nest? Typical Osprey nesting habitat.
After the banning of DDT in 1972, osprey populations rebounded. The population of ospreys dropped drastically from the early 1950s to the 1970s. Nesting in North America, ospreys spend the winter in the southern United States, Central, and South America. As the name suggests, ospreys feed almost exclusively on fish, and although they are incapable of swimming, they dive into the water to catch fish from heights of up to 90 feet. Associated with shorelines and various bodies of water, ospreys’ large nests can be observed readily from afar.
Ospreys, scientifically known as Pandion haliaetus, are one of the most popular birds in North America.
