Flock Bronzewing

识别特征

The flock bronzewing is the most nomadic of the Australian pigeons, and it is difficult to mistake for other Australian species. Fully grown flock bronzewings can range in length from 280–305 mm with a wing length of 189–216 mm. Its weight can range from 260–320 grams.<p>The adult male's head is black except for the white forehead, patch on lower throat, and white line that runs from behind the eye almost enclosing ear coverts forming a broken ring. The upperparts and wings are a reddish sandy brown. The primary coverts and alula are grey with white margins. The primaries are grey with chestnut inner webs; all but the outer three are tipped white. The secondaries are grey except for the inner secondaries, which have a chestnut inner web. The iris is dark brown and the bill is black.<p>The upper section including the crown and forehead are sandy-brown. The black and white chin, face and throat markings are very dull compared to the male. There is a sandy-brown section across the foreneck and another difference is that the primaries are not tipped white.<p>Juveniles look most similar to the adult females, but have some differences such as missing or less distinct facial markings; the primaries and some secondaries are tipped brown and the bill is horn- coloured.

English ornithologist John Gould first described the flock bronzewing, known then as the harlequin bronzewing, in volume five of his book The Birds of Australia. It was originally listed under the genus Persitera. His first sighting occurred in 1839 along the Mooki River (upper section of Namoi River) within the Liverpool Plains, New South Wales.<p>A syntype of Columba (Peristera) histrionica Gould (Bds. Austr., 1841. Pt.2. (March 1), pl. (13) = 5 pl. 66 of bound volume), an adult male, is held in the vertebrate zoology collection of National Museums Liverpool at World Museum, with accession number NML-VZ D1486b. The specimen was collected in Namoi, New South Wales in December 1839. The specimen was purchased by John Gould and came to the Liverpool national collection via the 13th Earl of Derby’s collection which was bequeathed to the people of Liverpool in 1851. There are two other syntypes in the collections of the Academy of Natural Sciences of Philadelphia.

分布与栖息地

The flock bronzewing is most abundant within the Barkly Tablelands of eastern Northern Territory and Western Queensland; however, their range is quite large and they will occasionally be found in the Kimberly region of Western Australia, northern South Australia and northwestern New South Wales. They are no longer found in the type locality on the Liverpool Plains, NSW. More than any other Australian pigeon, the flock bronzewing is adapted to the arid plains of the continent. The preferred habitat is open grassland plains, clumped grasses and small shrubs with open spaces. A major area for this type of habitat where the flock bronzewings are present is within the grass plains of the Barkly Tableland.
