The subspecies are fairly close in size, with the nominate subspecies averaging 1.53 kg (3.4 lb), P. h. carolinensis averaging 1.7 kg (3.7 lb) and P. h. cristatus averaging 1.25 kg (2.8 lb). [1] There is evidence for regional decline in South Australia where former territories at locations in the Spencer Gulf and along the lower Murray River have been vacant for decades. It is brown on the upperparts and predominantly greyish on the head and underparts. Spread the word. Most taxonomic authorities consider the species cosmopolitan and conspecific. [28], In the late 19th and early 20th centuries, the main threats to osprey populations were egg collectors and hunting of the adults along with other birds of prey,[36][62] but osprey populations declined drastically in many areas in the 1950s and 1960s; this appeared to be in part due to the toxic effects of insecticides such as DDT on reproduction. About This Bird One of the most widely distributed raptors in the world, and one of the few that specializes in eating fish, the Osprey nests along the coastlines, rivers, and large lakes of five continents and many islands. There was a medieval belief that fish were so mesmerised by the osprey that they turned belly-up in surrender, This page was last edited on 31 December 2020, at 20:53. Our email newsletter shares the latest programs and initiatives. Migrating Ospreys are sometimes seen far from water, even over the desert. 1 brood per year. This allows them to easily grasp fish with two toes pointing to the front and two pointing to the rear. [44], Ospreys usually mate for life. Text © Kenn Kaufman, adapted from [2] The genus, Pandion, is the sole member of the family Pandionidae, and used to contain only one species, the osprey (P. haliaetus). Courtship displays include pair circling high together; male may fly high and then dive repeatedly in vicinity of nest site, often carrying a fish or stick. Ro-Ro/Passenger Ship IMO: 9064059. They are widespread in the Northern Hemisphere and Australia. [29] It is possible it may once have ranged across Vanuatu and Fiji as well. It is also called Fish Hawk or Fish Eagle due to its heavy reliance on fish as a component of its diet. The genus Pandion was described by the French zoologist Marie Jules César Savigny in 1809.[3][4]. [45] When food is scarce, the first chicks to hatch are most likely to survive.

[55] Some ospreys from Florida migrate to South America. European breeders winter in Africa. A number of claw fossils have been recovered from Pliocene and Pleistocene sediments in Florida and South Carolina. As is the osprey to the fish, who takes it The Osprey has other adaptations that suit its fish-eating diet: reversible outer toes, long talons, and barbed pads under their toes that help the bird hold on to slippery fish. [14], The origins of osprey are obscure;[16] the word itself was first recorded around 1460, derived via the Anglo-French ospriet and the Medieval Latin avis prede "bird of prey," from the Latin avis praedæ though the Oxford English Dictionary notes a connection with the Latin ossifraga or "bone breaker" of Pliny the Elder. [19], The osprey is 0.9–2.1 kg (2.0–4.6 lb) in weight and 50–66 cm (20–26 in) in length with a 127–180 cm (50–71 in) wingspan. [25] Possibly because of the banning of DDT in many countries in the early 1970s, together with reduced persecution, the osprey, as well as other affected bird of prey species, have made significant recoveries. The same climate change-driven threats that put birds at risk will affect other wildlife and people, too. dense plumage which is oily and prevents its feathers from getting waterlogged. The subfamily Accipitrinae includes goshawks, sparrowhawks, sharp-shinned hawks and others. Audubon protects birds and the places they need, today and tomorrow. [6], The osprey is unusual in that it is a single living species that occurs nearly worldwide. Photo: Larry Stamm/Audubon Photography Awards. It is straightforward to determine the sex in a breeding pair, but harder with individual birds. Sharp-shinned hawk, a small member of the Accipitrinae subfamily. To ease this problem, posts are sometimes erected to provide more sites suitable for nest building. Red-tailed Hawks have much stouter and broader wings (without the Osprey’s kink at the wrists) and a shorter, broader tail. [33] It typically takes fish weighing 150–300 g (5.3–10.6 oz) and about 25–35 cm (9.8–13.8 in) in length, but the weight can range from 50 g (1.8 oz) to 2 kg (4.4 lb). Nest site is usually on top of large tree (often with dead or broken top) not far from water. One of the most widespread raptors in the world, the osprey is also one of the most unusual and is the only member of its own bird family, Pandionidae. Osprey platforms typically have fence-like side boards around the perimeter about 1′ … Only occasionally, when fish aren't available, will the Osprey eat small mammals, birds, or reptiles. In the poem, the osprey is considered to be an icon of fidelity and harmony between wife and husband, due to its highly monogamous habits. Although migrating predominantly in the day, they sometimes fly in the dark hours particularly in crossings over water and cover on average 260–280 km (160–170 mi) per day with a maximum of 431 km (268 mi) per day. [43] Osprey-watch.org is the global site for mapping osprey nest locations and logging observations on reproductive success. It is the sole member of its subfamily, “Pandioninae.” A diving osprey plunges into a Highland loch to catch a fish supper. In the eastern U.S., breeding occurs from Maine to Florida. Or take action immediately with one of our current campaigns below: The Audubon Bird Guide is a free and complete field guide to more than 800 species of North American birds, right in your pocket. This subfamily are mainly woodland birds with long tails and high visual acuity. Their toes are of equal length and (with the exception of owls) Osprey is the only raptor with a reversible hind toe, almost certainly an adaptation to its fish diet. This is particularly helpful when they grab slippery fish. It’s the least you can do.

The osprey differs in several respects from other diurnal birds of prey. An osprey flies over the water to hunt. The birds have long legs and large feet with specialized barbs on the pads, hooked talons, and a reversible outer toe. —Don Lyon, Director of Conservation Science, National Audubon Society *** Learn more! It is a large raptor, reaching more than 60 cm (24 in) in length and 180 cm (71 in) across the wings. Feeds mainly on fish. Osprey Ambassador @nimsdai and his team are taking their time to get fully prepared for the next phase of their K2 Winter Expedition. The platform plans and materials list, available online, have been utilized by people from a number of different geographical regions. Listen to Osprey on bird-sounds.net - a comprehensive collection of North American bird songs and bird calls. Mortality can also occur through mishaps with human utilities, such as nesting near electrical wiring or collisions with aircraft. Osprey: This large raptor has dark brown upperparts, white underparts, faint breast band, small white head with dark crown, eye stripe and bill, gray legs and feet. Along coastlines, lakes, and rivers almost worldwide, the Osprey is often seen flying over the water, hovering, and then plunging feet-first to catch fish in its talons. Its toes are of equal length, its tarsi are reticulate, and its talons are rounded, rather than grooved. Many ospreys from Vermont are likely to spend their winters as far south as Ce… So-called "osprey" plumes were an important item in the plume trade of the late 19th century and used in hats including those used as part of the army uniform. 1 brood per year. Rivers, lakes, coast. Creamy white, blotched with brown. [59], Swedish ospreys have a significantly higher mortality rate during migration seasons than during stationary periods, with more than half of the total annual mortality occurring during migration. Inspired designs on t-shirts, posters, stickers, home decor, and more by independent artists and designers from around the world. The same study found an average of 0.66 young fledged per year per occupied territory, and 0.92 young fledged per year per active nest. [13], The genus name Pandion derives from the mythical Greek king of Athens and grandfather of Theseus, Pandion II. They have a fairly tight construction, and the sticks that compose the nest tend to be smaller than those used for eagle or osprey nests (sticks generally 1-2 inches in diameter). Legal Notices Privacy Policy Contact Us. Mostly white head and underparts; dark brown back. Other schemes place it alongside the hawks and eagles in the family Accipitridae—which itself can be regarded as making up the bulk of the order Accipitriformes or else be lumped with the Falconidae into Falconiformes. It is, thus, of similar size to the largest members of the Buteo or Falco genera. Wings held at a distinct angle in flight, under wing showing barred flight feathers and diagnostic dark patches on the fore wing. The eggs are whitish with bold splotches of reddish-brown and are about 6.2 cm × 4.5 cm (2.4 in × 1.8 in) and weigh about 65 g (2.3 oz). Also nests on utility poles, duck blinds, other structures, including poles put up for them.

Unlock thousands of full-length species accounts and hundreds of bird family overviews when you subscribe to Birds of the World. Their heads are white with a dark brown through their eyes. Both are primarily fish eaters that build large stick nests, but the similarities diminish with further details or close-up viewing. If there are no nesting sites available, young ospreys may be forced to delay breeding. It is brown above and white below, with some white on the head. It is an uncommon to fairly common winter visitor to all parts of South Asia,[30] and Southeast Asia from Myanmar through to Indochina and southern China, Indonesia, Malaysia and the Philippines. However, the Osprey is highly specialized for eating fish and does not stray from this diet unless necessary. Audubon’s scientists have used 140 million bird observations and sophisticated climate models to project how climate change will affect this bird’s range in the future. The osprey and owls are the only raptors whose outer toe is reversible, allowing them to grasp their prey with two toes in front and two behind. It can be constructed with 2x4s or 2x6s or both and mounted on most any wood post (possibly steel or concrete). The breast band of the male is also weaker than that of the female, or is non-existent, and the underwing coverts of the male are more uniformly pale. Zoom in to see how this species’s current range will shift, expand, and contract under increased global temperatures. In flight, holds wings with a kink in the wrist (shaped like an [58] In the Mediterranean, ospreys show partial migratory behaviour with some individuals remaining resident, whilst others undertake relatively short migration trips. [61], The osprey has a large range, covering 9,670,000 km2 (3,730,000 sq mi) in just Africa and the Americas, and has a large global population estimated at 460,000 individuals. Although Pandion II was not used to name a bird of prey, Nisus, a king of Megara, was used for the genus. After a successful strike, the bird rises heavily from the water and flies away, carrying the fish head-forward with its feet.

Age of young at first flight averages about 51-54 days. To date there have been two extinct species named from the fossil record. It is an unusual species, not closely related to any other bird of prey. Young: Female remains with young most of time at first, sheltering them from sun and rain; male brings fish, female feeds them to young. Found near water, either fresh or salt, where large numbers of fish are present. Along coastlines, lakes, and rivers almost worldwide, the Osprey is often seen flying over the water, hovering, and then plunging feet-first to catch fish in its talons. [45] The breeding season varies according to latitude; spring (September–October) in southern Australia, April to July in northern Australia and winter (June–August) in southern Queensland. Studies of Swedish ospreys showed that females tend to migrate to Africa earlier than the males. Almost entirely fish. Flies slowly over water, pausing to hover when fish spotted below; if fish is close enough to surface, the Osprey plunges feet-first, grasping prey in its talons. Many are renovated each season, and some have been used for 70 years. Age of young at first flight averages about 51-54 days. Let us send you the latest in bird and conservation news.

[28] In the islands of the Pacific it is found in the Bismarck Islands, Solomon Islands and New Caledonia, and fossil remains of adults and juveniles have been found in Tonga, where it probably was wiped out by arriving humans. It is found in temperate and tropical regions of all continents, except Antarctica. [52] Endoparasitic trematodes (Scaphanocephalus expansus and Neodiplostomum spp.) The osprey tolerates a wide variety of habitats, nesting in any location near a body of water providing an adequate food supply.
