Ospreys eat mainly fish. They have numerous adaptations that make them particularly suited for hunting fish. Their eyesight is specifically developed to be able to see objects underwater from the air, and their outer toe is reversible, allowing them to more easily grasp fish in their claws. They can also close their nostrils to avoid inhaling water while diving. Their feathers are covered in an oily coating that helps keep their plumage from absorbing water.
In areas near water, ospreys are often a common sight, hovering in the air as they scan for fish, and then performing fantastic dives in order to subdue their prey.
Ospreys create a large nest from sticks, wood and seaweed. Occasionally these nests are created on man-made structures like utility poles, which can lead to power outages. Some areas have erected specific elevated platforms to serve as nesting sites for ospreys.
Osprey couples usually stay together for life. During the breeding season, the female lays between two and four eggs, which hatch in about 35-43 days.
There are many different subspecies of osprey found throughout the world, but they share the same basic characteristics. The wingspan ranges from four feet to six feet, and they can weigh up to four and a half pounds.
The osprey’s feathers are dark brown above, and white on the underside. Its head is mostly white, with a dark “mask” over the eyes. The female has a prominent brown band of feathers across the chest, while this is largely reduced or not present in most males.
The osprey is one of the most widespread birds of prey in the world, second only to the peregrine falcon. It is found nearly worldwide, on every continent except Antarctica. Its habitat includes virtually any region with a temperate or tropical climate that’s near a body of water.
Due to its wide-ranging distribution, the osprey features in literature and folklore from many cultures. They were mentioned by the Ancient Roman author Pliny the Elder, and feature in Chinese folk poems, as well as European medieval legends. The bird is mentioned in a poem by Irish Poet William Butler Yeats, and is referenced in a play by Shakespeare.
An American military aircraft known as the V-22 Osprey takes its name from the bird.
The osprey is a species of Least Concern. Its population is estimated at almost a half a million birds worldwide. Populations declined in many regions during the middle of the 20th century, largely due to the use of pesticides such as DDT. This pesticide caused the shells of bird eggs to become thin, affecting successful reproduction rates. However, like many other birds of prey species, the osprey made a substantial recovery after the ban of DDT’s use.
