Physical description Click here for a physical description Eastern Ospreys are medium-sized birds of prey. Their overall appearance is greyish-brown, with a light grey front (throat, belly, vent) and brownish dark-grey back (mantle, wings, uppertail). The face has prominent grey eye stripes around eyes with yellow irises. The underwing pattern is scalloped light-grey (leading edge) to mid-grey (flight feathers) to dark grey (alulas and tips of primaries). The bill is dark-grey; the legs and feet are grey, with dark-grey talons. The only difference between the sexes is that female Ospreys have a streaked breast band, while males don't. Juvenile Eastern Ospreys have a heavier chest band than adult females, which is also more brownish, and a more brownish head.

Taxonomy, classification See Osprey at Wikipedia . Click here for classification information The Eastern Osprey, Pandion cristatus, is no longer considered to be a race of the Osprey, Pandion haliaetus, but has now been given full species status. Ospreys (Pandion haliaetus) were seen by us in Oman and in Europe.

Range, habitat, finding this species Click here for information on habitat and range The overall distribution of this species can be assessed, and specific locations where birds have been spotted can be found, based on individual sighting reports submitted by birdwatchers to ebird.org . The global distribution of the Eastern Osprey is available HERE . Eastern Ospreys are found in eastern Indonesia, southern Papua New Guinea, the Solmon Islands, Fiji and in Australia. Eastern Ospreys populate almost the entire Australian coastline, except for some parts of the South coast (the Nullarbor and the South coast of VIC). Apart from the lower courses of some major rivers, Eastern Ospreys are not usually found farther inland. They are present on some islands in the Timor Sea towards Indonesia. Eastern Ospreys hunt in mangrove marshes, estuaries and along rivers, but also coastal waters and around offshore islands. Where to look? How to find this species? Eastern Ospreys are most easily found riding updraughts along the coastline of the continent, especially near headlands. They will often hover facing into the breeze, searching for prey in the coastal water below.

Sightings Click here for sighting information We first saw a family of Eastern Ospreys in Australia near the estuary of the Greenough River, South of Geraldton, WA, in July 2003. The species was spotted in the same area in June 2011 by S. Kirkby. Over the years we, and various contributors, have found Eastern Ospreys in many different locations along the East coast of Australia, in both QLD and NSW. Several contributors report finding Eastern Ospreys regularly along the entire coastline of WA, from the far South to the northern coastline near Broome, WA. C. Hayne reports that Eastern Ospreys appear to be colonizing the area near Moree, NSW, moving downstream along the Mehi and Gwydir Rivers towards the centre of the continent. Various sightings have been reported in 2013 (Moree town common and North of Moree) and 2014 (North of Moree and at Whittaker's Lagoon, 25 km West of Moree). An Eastern Osprey was spotted again in inland NSW by S. Barwick, who found a bird hunting fish in a large waterhole of the Castlereagh River in the township of Gilgandra, NSW, in June 2017. The bird was spotted by M. Windeyer at the same location again in July 2017. J. Greaves reports spotting an Eastern Osprey in Alyangula, Groote Eylandt, NT, in September 2014. P. Brown and B. Hensen report finding Eastern Osprey at Casuarina Coastal Reserve, Darwin, NT, in June/July 2018, where they were found nesting at the time. Since then they have been found there semi-regularly.

Behaviour

Social behaviour: Territorial

Mobility: Sedentary

Elementary unit: Pair

NB: The Eastern Osprey, Pandion cristatus, is the only sedentary Osprey. All races of the now distinct species Pandion haliaetus are migratory.

Although usually close to the Australian coastline, Eastern Ospreys are occasionally found farther inland, especially along major inland rivers.

Food, Diet

Adults: Fish

Dependents: As adults

Water intake: None

All raptors are carnivores. Eastern Ospreys feed on fish, which they can catch up to 1 m below the water surface.

During the first few weeks, raptors feed their chicks with pieces of meat. Later on in their development, the chicks learn to tear apart their parents' prey.
