Physical description Click here for a physical description Grey Goshawks are small raptors. Their plumage comes in two morphologies, grey and white. Grey morphology birds have a light-grey head, neck and mantle, grey wings with dark-grey tips and a grey tail. The underwing pattern is almost white, with light-grey tips of the primaries. White morphology birds have an all-white plumage, with faint light-grey edges of the wing feathers. Both morphologies have a yellow bill with black tip and yellow legs and feet with black talons. Juvenile grey morphology Grey Goshawks have a grey and white mottled breast. "Raptors" (or "birds of prey"), most prominently, but also some species of waders, show a pronounced "dimorphism", i.e. a difference between male and female birds - not just in the appearance of the plumage, but in other, important properties, such as size or strength. Here we explain why.

Taxonomy, classification See Grey Goshawk at Wikipedia .

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 Grey Goshawk is available HERE . Grey Goshawks are found in southern coastal New Guinea and in Australia. Grey Goshawks, nominate race "novaehollandiae", are found along the coastal fringe of Australia, from about Eighty Mile Beach in WA, along the Top End of the NT and all of Cape York peninsula, down the East coast and the South-East and South coast, to about Adelaide, SA. They occasionally venture into the hinterland of these coastal regions, up to a few hundred km inland. They are also found on islands along Bass Strait and in Tasmania. Grey Goshawks hunt mostly in and around dense, mostly coastal forests and heathland.

Twitcher's tip

Note that, by the time they fledge (i.e., leave their nest), the young of all species of raptors - apart from the tail and wing feathers (which are still growing) - are already full adult-size.

Eggs

"boyanga", "booyanga", "derinya", "dirandil", "koomura", "mirk", "ngampu", "nooluk", "pateena", "pum-pum" = Egg; "dirundirri" = eggs [Aboriginal]; "gawu" = eggs [gamilaraay]

Size: 47 x 37 mm

Colour: Creamy, with light-brown patches

Shape: Tapered oval

Behaviour

Parrots and cockatoos can quite often be seen to pester raptors, but sometimes the roles are reversed and the raptors use flocks of other bird species to hide in before striking their prey.

Food, Diet

Adults: Small mammals, birds, lizards

Dependents: As adults

Water intake: None

All raptors are carnivores.

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.
