what do ospreys eat

[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. [70], six of 10000 land based bird species include.

[55] Some ospreys from Florida migrate to South America. Some 22% of surviving young either remained on the island or returned at maturity to join the breeding population. 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. [23], The sexes appear fairly similar, but the adult male can be distinguished from the female by its slimmer body and narrower wings.

The osprey is used as a brand name for various products and sports teams, such as the Ospreys (a Welsh Rugby team) and the Seattle Seahawks (an American football team of the National Football League). It is a large raptor, reaching more than 60 cm (24 in) in length and 180 cm (71 in) across the wings.

The osprey or more specifically the western osprey (Pandion haliaetus) — also called sea hawk, river hawk, and fish hawk — is a diurnal, fish-eating bird of prey with a cosmopolitan range.

Ospreys eat live fish almost exclusively, although they will sometimes scavenge dead fish or hunt for other animals if necessary. The osprey or more specifically the western osprey (Pandion haliaetus) — also called sea hawk, river hawk, and fish hawk — is a diurnal, fish-eating bird of prey with a cosmopolitan range. Rarely, polyandry has been recorded.

Mortality can also occur through mishaps with human utilities, such as nesting near electrical wiring or collisions with aircraft.

[27], There is a 1,000 km (620 mi) gap, corresponding with the coast of the Nullarbor Plain, between its westernmost breeding site in South Australia and the nearest breeding sites to the west in Western Australia. Ospreys are superb fishers and indeed eat little elseâfish make up some 99 percent of their diet. There are four generally recognised subspecies, although differences are small, and ITIS lists only the first two.[3].

A number of claw fossils have been recovered from Pliocene and Pleistocene sediments in Florida and South Carolina.

Their nostrils have the ability to stay sealed while they dive underwater, and their talons have barbs that effectively keep their prey from escaping their grasp.

The head is white with a dark mask across the eyes, reaching to the sides of the neck.

[2] The genus, Pandion, is the sole member of the family Pandionidae, and used to contain only one species, the osprey (P. haliaetus).

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.

[12] Another Pandionidae claw fossil was recovered from Early Oligocene deposits in the Mainz basin, Germany, and was described in 2006 by Gerald Mayr.

The call is a series of sharp whistles, described as cheep, cheep or yewk, yewk.

Their white heads also have a distinctive black eyestripe that goes down the side of their faces. [5] A short tail and long, narrow wings with four long, finger-like feathers, and a shorter fifth, give it a very distinctive appearance. The newly hatched chicks weigh only 50–60 g (1.8–2.1 oz), but fledge in 8–10 weeks. [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.

[20][21], The upperparts are a deep, glossy brown, while the breast is white and sometimes streaked with brown, and the underparts are pure white. [25] It is found in summer throughout Europe north into Ireland, Scandinavia, Finland and Great Britain though not Iceland, and winters in North Africa. Its toes are of equal length, its tarsi are reticulate, and its talons are rounded, rather than grooved. [31], The worldwide distribution of the species is unusual for land-based birds, and only recognised in five other species.[32][a]. [5] It has always presented something of a riddle to taxonomists, but here it is treated as the sole living member of the family Pandionidae, and the family listed in its traditional place as part of the order Falconiformes. [36][47][48][49][50] However, kleptoparasitism by bald eagles, where the larger raptor steals the osprey's catch, is more common than predation. But we are not the only predators; hawks, eagles, Peregrine Falcons, ospreys will eat owls.

A few authorities split the osprey into two species, the western osprey and the eastern osprey. [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.

[17][18] However, this term referred to the Bearded vulture. The bill is black, with a blue cere, and the feet are white with black talons. [26] In Australia it is mainly sedentary and found patchily around the coastline, though it is a non-breeding visitor to eastern Victoria and Tasmania. To minimize wind resistance, ospreys face their fish forwards while flying.

[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. Humans eat all kinds of meat including an owl.

The wing chord measures 38 to 52 cm (15 to 20 in), the tail measures 16.5 to 24 cm (6.5 to 9.4 in) and the tarsus is 5.2–6.6 cm (2.0–2.6 in).

Ospreys have evolved and adapted to become highly efficient hunters of fish. [44], Ospreys usually mate for life. dense plumage which is oily and prevents its feathers from getting waterlogged. Three subspecies are usually recognized; one of the former subspecies, cristatus, has recently been given full species status and is referred to as the eastern osprey.

[34], Occasionally, the osprey may prey on rodents, rabbits, hares, other birds,[35] and small reptiles.[36]. [33][39] As wide as 2 meters and weighing about 135 kg, large nests on utility poles may be fire hazards and have caused power outages.

So what do bluegill eat?

They have gripping pads on their feet to help them pluck fish from the water with their curved claws and carry them for great distances. have been recorded in wild ospreys.[53]. It possesses specialised physical characteristics and exhibits unique behaviour to assist in hunting and catching prey. In flight, ospreys will orient the fish headfirst to ease wind resistance. Quote: Fish make up 99% of the Osprey's diet.

It is found on all continents except Antarctica, although in South America it occurs only as a non-breeding migrant. Eagles often force osprey to drop fish that they have caught and steal them in midair. [11] Pandion homalopteron was named by Stuart L. Warter in 1976 from fossils of Middle Miocene, Barstovian age, found in marine deposits in the southern part of California. [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). Ospreys hunt by diving to the water's surface from some 30 to 100 feet up. As is the osprey to the fish, who takes it

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. [29] It is possible it may once have ranged across Vanuatu and Fiji as well. Most taxonomic authorities consider the species cosmopolitan and conspecific. The typical lifespan is 7–10 years, though rarely individuals can grow to as old as 20–25 years. [23], The juvenile osprey may be identified by buff fringes to the plumage of the upperparts, a buff tone to the underparts, and streaked feathers on the head. It has a worldwide distribution and is found in temperate and tropical regions of all continents except Antarctica.

Artificial nesting platforms are common in areas where preservationists are working to reestablish the birds.
