The Silktail (Lamprolia victoriae), is a species of [] endemic to Fiji. It is the only member of the genus Lamprolia. This beautiful bird looks superficially like a diminutive bird-of-paradise but it is actually closely related to the fantails.
Taxonomy and Systematics
The systematic position of the silktail has been a long-standing mystery. When describing the species Otto Finsch wrote "I scarcely remember a bird which has puzzled me in respect of its generic position so much as this curious little creature". It has variously been placed with the birds-of-paradise (Paradisaeidae), the Australasian robins (Petroicidae) and the fairy-wrens (Maluridae). Since 1980 it has generally been considered to be an ancient and aberrant monarch flycatcher. A 2009 molecular study placed the species as a sister to the pygmy drongo of the highlands of New Guinea, and the two of these as a sister clade to the fantails (Rhipiduridae).
The genus Lamprolia is named after the diminutive of lampros (Ancient Greek) for splendid or brilliant. Finsch named the species after Victoria, eldest daughter of Queen Victoria, who was then Crown Princess of Germany. The subspecies Lamprolia victoriae kleinschmidti is named for Theodor Kleinschmidt, a collector from Museum Godeffroy in Hamburg, who obtained the first specimens.
The silktail is a small black bird, measuring around 12 centimetres (4.7 in) and weighing 16 to 21 g (0.56–0.74 oz). It is a small, dumpy bird with long rounded wings, and a short rounded tail. The plumage of the male is velvet black with metallic blue iridescent spangling on the crown and breast, and silky white lower-back patch that travels most of the length down the tail. The margin of the tail is black, sometimes this tip has the same iridescence as other parts of the body. The female is similar to the male, except less glossy, and immature birds are duller than the adults and may have buffy rumps and backs. The irises of this species are dark, and the legs and bill are blackish. The bill is heavy and slightly hooked at the end. The legs are long and the feet strong. The subspecies Lamprolia victoriae kleinschmidti is smaller than the nominate race and has more iridescence plumage than the nominate.
Distribution and Habitat
The silktail is endemic to forests of Taveuni and Vanua Levu in [[wikipedia:Fiji|Fiji]. It occurs widely on Taveuni, but has a more restricted distribution on Vanua Levu, where it only occurs in the east of the island on the Natewa Peninsula. It occurs in mature wet rainforests, as well as forest patches, and is also found in human-modified habitats such as logged forests and in plantations near patches of natural forest.
The silktail can be quite elusive and difficult to see, but may also be confiding and approachable. It is usually very active at dawn, and is encountered either singily or in small flocks.
Status and Conservation
The silktail is a restricted range species, being present only on two islands in Fiji. It is absent from apparently suitable habitat on Vanua Levu, where it only occurs on the Natewa Peninsula. It is more widespread on Taveuni. Forest clearance for mahogany plantations and general forest clearance within its range have led to the species being listed as vulnerable in 1994, however this was downgraded to near threatened in 2006. While its habitat is being lost, it is not yet severely fragmented. On Taveuni forest clearance is slower than Vanua Levu and the population is estimated to be around 5,000-8,000 pairs. The population in Vanua Levu is smaller, at around 3,000-6,000 pairs. A reserve for the species has been proposed on Vanua Leu, but has not yet been gazetted. On the island of Taveuni the species occurs within the Ravilevu Nature Reserve and the Bouma National Heritage Park.
