Physical description Click here for a physical description Red Goshawks are relatively small raptors. They have a highly cryptic plumage. The female is much larger than the male. The head is greyish, heavily streaked with bown and rufous tints. The nape of the neck of both sexes shows a small crest. The front is greyish-rufous, with dark-brown streaks, while the back is dark-brown with rufous edge-lining. The wing feathers are mostly barred mid- to dark-grey, with rufous lining. The tail is barred mid- to dark-grey; the upper legs are covered with rufous feathers. Males have a richer-rufous breast and a paler-grey head than females. The eyes have yellow irises, those of females being deeper orange-yellow than those of males, which are paler yellow. The bill of both sexes is dark-grey with a light-grey cere; the legs are yellow, with black talons. "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 Red 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 Red Goshawk is available HERE . Red Goshawks are endemic to the Australian continent. They are mostly found in tropical Australia, i.e. the Top End of the NT, but occasionally also farther inland, from the Kimberley, WA, through the northern part of the NT, along the southern end of the Gulf of Carpentaria, throughout Cape York peninsula in QLD, down to a line connecting roughly Derby, WA, with Mt. Isa, QLD and Emerald, QLD. From there, their (non-breeding?) range extends to the South, along the QLD/NSW East coast and adjacent Great Dividing Range. On the coast, they go as far as the Hunter Wetlands NP, Newcastle, NSW, while inland they are found to about Coolah Tops NP, near Coolah, NSW. Although they have a preference for near-coastal forest, they are also found farther inland, in drier sclerophyll forest and woodland.

Sightings Click here for sighting information B. Hensen reports spotting a nesting pair of Red Goshawks at Bitter Springs, Mataranka, NT, in August 2006. H. Mouritsen reports finding a nesting pair of Red Goshawks near Gunlom Falls, Mary River, Kakadu NP, NT, in October 2015. B. Hensen also found a Red Goshawk on its nest in Kakadu NP, NT, in July 2018. P. Brown reports spotting a Red Goshawk near its nest in Litchfield NP, NT, in October 2020. Another was spotted at the same location, again at its nest, in September 2021. J. Boettcher, FNQ Nature Tours reports finding Red Goshawks nesting at Rinyirru (Lakefield) NP, near Cape Melville, Cape York peninsula, QLD, in September 2020.

Breeding information

Breeding season: May - Dec

Eggs: 1 - 2

Incubation period: 40-43 days

Fledging age: ca. 50 days

The breeding season of Red Goshawks depends on geographic latitude.

Nest building: ?

Incubation: Female

Dependent care: Female & male

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.

For species of raptors with a pronounced size dimorphism between the sexes (the female is always bigger than the male), the obvious consequence is that a female near-fledging age chick already dwarfs not only any male siblings, but also its father.

Nest

"bungobittah", "lar", "malunna", "jindi" [bundjalung] = nest [Aboriginal]

Type: Basket

Material: Sticks, green leaves

Height above ground: >10? m

Note that, contrary to many other raptors' habits, Red Goshawks build their nests into live eucalypt trees, not dead ones.
