The New Britain sparrowhawk (Tachyspiza brachyura) is a threatened species of bird of prey. It is endemic to two Papua New Guinea islands, New Britain and New Ireland. Even in 1934 Ernst Mayr, in his survey of mountain bird life during the Whitney South Sea Expedition, found the New Britain sparrowhawk to be very rare. [2] This species was formerly placed in the genus Accipiter .

Description

These sparrowhawks are grey with a white underbelly and orange accents on the neck. They are often characterized by their large feet. They are the only hawk in New Britain or the Solomon Islands that has a middle toe that is longer than the rest. [2] The feet of the New Britain sparrowhawks are pale yellow. These small birds only grow to be 27–34 cm long.

Ecology

This species lives in tropical to subtropical, moist montane forest. The altitudes reach 1,200 to 1,800 m. New Britain sparrowhawks nest like other birds, where they raise their young. Very little is known about this species because it is so rare and the areas in which it lives have not been thoroughly studied. [3]

Conservation

it is estimated that the population is only between 1,000 and 2,499 individuals. [3] The main threat to the continued existence of this species is habitat destruction which has led to the birds' decline in lowland forests. The clearing of forest on the small islands leaves the species with less habitat, and a far less safe environment – leading to their vulnerability. No conservation measures are known to have been taken; however it has been proposed that surveys be made to assess population size and observe nests, as well as to map the remaining forest. There are also plans to lobby for large community-based conservation areas. [3]

<i>Accipiter</i> Genus of birds

Accipiter is a genus of birds of prey in the family Accipitridae. With around 50 recognized species it is the most diverse genus in its family. Most species are called goshawks or sparrowhawks, although with the exception of the American goshawk almost all New World species are simply known as "hawks". They can be anatomically distinguished from their relatives by the lack of a procoracoid foramen. Two small and aberrant species usually placed here do possess a large procoracoid foramen and are also distinct as regards DNA sequence. They may warrant separation in the old genus Hieraspiza.

<span class="mw-page-title-main">Shikra</span> Species of bird

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.

The species is globally listed as least concern, although it is listed as endangered in Japan and protected in China.
