The Fiji goshawk (Tachyspiza rufitorques) is a species of bird of prey in the family Accipitridae. It was once considered to be the same species (conspecific) as the brown goshawk of Australia and New Caledonia. It is endemic to Fiji, where it occurs on the larger islands of Viti Levu, Vanua Levu, Taveuni, Kadavu, Gau and Ovalau. [2] It occupies a range of wooded habitats in Fiji, from natural rainforest to coconut plantations and urban gardens and parks. [3]

Description

The Fiji goshawk ranges in size from 30–40 cm, making it medium-sized for its genus. It exhibits sexual dimorphism, with the females being larger than the males. [3] It has long legs and a long tail. The plumage is unmistakable within its range, having a grey head, back, tail and wings and dull pink undersides and collar. The plumage of the juvenile is distinct from the adult, being all over brown with a highly streaked breast. [2]

Diet

The Fiji goshawk feeds on birds as large as pigeons, insects, introduced rodents and reptiles. [3] and have also been recorded feeding on freshwater prawns from the family Palaemonidae, [4] as well as freshwater fish. This species hunts both from perches or flying. Prey may be snatched with either a slow and stealthy glide or a quick flapping attack. Prey may be chased into cover and they will actively harass and attempt to flush concealed prey.

Breeding

Fiji goshawks are seasonal breeders, with the breeding season occurring between July and December. [5] Most eggs are laid between September and October. The nest is a platform of sticks located high in a lightly vegetated tree. The typical clutch size is two to three eggs (occasionally four), of which up to two chicks are commonly fledged. [3]

History

Although the species is today considered to be endemic to Fiji, fossil bones attributed to this species have been found on the island of 'Eua in Tonga. [6] The species may once have occurred in the Lau group of Fiji as well. [7] Fiji goshawks will occasionally take chickens and are often shot. They are nevertheless common and live at high densities.

The Accipitridae is one of the four families within the order Accipitriformes, and is a family of small to large birds of prey with strongly hooked bills and variable morphology based on diet. They feed on a range of prey items from insects to medium-sized mammals, with a number feeding on carrion and a few feeding on fruit. The Accipitridae have a cosmopolitan distribution, being found on all the world's continents and a number of oceanic island groups. Some species are migratory. The family contains 256 species which are divided into 12 subfamilies and 75 genera.

The shikra is a small bird of prey in the family Accipitridae found widely distributed in Asia and Africa where it is also called the little banded goshawk. The African forms may represent a separate species but have usually been considered as subspecies of the shikra. The shikra is very similar in appearance, as well as behavior, at least to some degree, to other species including the Chinese sparrowhawk, Eurasian goshawk and Eurasian sparrowhawk. They have a sharp two note call and have the typical flap and glide flight. Their calls are imitated by drongos and the common hawk-cuckoo resembles it in plumage. This species was formerly placed in the genus Accipiter.

<span class="mw-page-title-main">Fiji parrotfinch</span> Species of bird in the family Estreldidae

The Fiji parrotfinch is a species of estrildid finch endemic to Fiji that was formerly considered to be a subspecies of the red-headed parrotfinch. This parrotfinch is a small, mainly green bird with a red head and tail and a stubby dark grey bill. It is found in both forested and open habitats, and has adapted well to man-made environments such as grasslands, pasture and gardens. Pairs have a courtship display in which they fly above the trees in an undulating flight, calling constantly. Breeding birds build a domed grass nest with a side entrance, and lay a clutch normally of four white eggs. Newly hatched chicks are naked and pink, with blue balls at the upper and lower corners of the gape, and black markings inside the mouth; older fledglings resemble the adults, but lack the red head colouring. The Fiji parrotfinch eats seeds, especially of grasses, and also readily feeds on insects and nectar. It forms small flocks of up to six birds after the breeding season.
