Justification
This species has a very large range, and hence does not approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence <20,000 km2 combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation). Despite the fact that the population trend appears to be decreasing, the decline is not believed to be sufficiently rapid to approach the thresholds for Vulnerable under the population trend criterion (>30% decline over ten years or three generations). The population size is very large, and hence does not approach the thresholds for Vulnerable under the population size criterion (<10,000 mature individuals with a continuing decline estimated to be >10% in ten years or three generations, or with a specified population structure). For these reasons the species is evaluated as Least Concern.

An immature Brown Goshawk flying in Tasmania, Australia

The Brown Goshawk (Accipiter fasciatus) is a medium-sized bird of prey in the family Accipitridae found in Australia and surrounding islands.

Contents

Description

Its upperparts are grey with a chestnut collar; its underparts are mainly rufous, finely barred with white. Thus it has similar colouring to the Collared Sparrowhawk but is larger. The flight is fast and flexible. The body length is 40–55 cm (15.7–21.7 in); the wingspan, 75–95 cm (29.5–37.4 in). Females are noticeably larger: adult males weigh 220 g (7.8 oz), and adult females, 355 g (12.5 oz).

Distribution and habitat

The Brown Goshawk is widespread through Australia, Tasmania, Wallacea, New Guinea, New Caledonia, Vanuatu and Fiji. It is found in forests and woodlands.

Feeding

It eats mainly birds; also small mammals, reptiles, amphibians; occasionally insects.

Breeding

It nests in tall trees on a platform of sticks and twigs lined with green leaves. The clutch size is usually three, sometimes two or four. The incubation period is about 30 days, with chicks fledging about 31 days after hatching.

Subspecies

There are twelve described subspecies:

  • A. f. fasciatus (nominate) - (Vigors et Horsfield, 1827)
  • A. f. buruensis - Stresemann, 1914
  • A. f. didimus - (Mathews, 1912)
  • A. f. dogwa - Rand, 1941
  • A. f. helmayri - Stresemann, 1922
  • A. f. natalis - (Lister, 1889)
  • A. f. polycryptus - Rothschild et Hartert, 1915
  • A. f. savu - Mayr, 1941
  • A. f. stresemanni - Rensch, 1931
  • A. f. tjendanae - Stresemann, 1925
  • A. f. vigilax - (Wetmore, 1926)
  • A. f. wallacii - (Sharpe, 1874)
