Bestimmung

This kingfisher has a red bill, a dark turquoise cap with brighter blue edges, blackish cheeks, and bluish-black upper parts. The under parts are white and the under-wing coverts are blue and white. The central tail feathers are elongated and their base is blue. It is similar in appearance to the buff-breasted paradise kingfisher (Tanysiptera sylvia) apart from the colour of the breast, and in some parts of Papua New Guinea, both birds coexist.

Taxonomie

The common paradise kingfisher was first described by the English zoologist George Robert Gray in 1859 based on specimens collected by Alfred Russel Wallace near "Dorey" (modern Manokwari in western New Guinea). Gray coined the current binomial name Tanysiptera galatea. The genus Tanysiptera had been introduced by the Irish zoologist Nicholas Aylward Vigors in 1825. The name Tanysiptera is from classical Greek tanusipteros meaning 'long-feathered'. The specific epithet galatea is from Greek mythology: Galatea was a sea nymph.<p>There are 15 recognised subspecies. Of these three occur on mainland New Guinea, 11 on the Maluku Islands to the west of New Guinea, and two on other islands.<p>The Biak paradise kingfisher (Tanysiptera riedelii) and the Kofiau paradise kingfisher (Tanysiptera ellioti) have sometimes been considered as subspecies of the common paradise kingfisher.

Verbreitung und Lebensraum

The common paradise kingfisher is found in the forested interior of New Guinea and on some of the offshore islands to the north. Its distribution is rather patchy and it mostly occurs below 500 m (1,600 ft) on the mainland and 820 m (2,700 ft) on Karkar Island. On some islands it is replaced by sister species; the Biak paradise kingfisher (T. riedelii) on Biak Island; the Kofiau paradise kingfisher (T. ellioti) on Kofiau Island; and the Numfor paradise kingfisher (T. carolinae) on Numfor Island. It seems that each of these island species originated from founding T. galatea birds which became isolated from the mainland birds and underwent a "genetic revolution". There were no particular biotic factors involved, but there was sufficient variation among the founding birds to encourage speciation, and the assortment of genes that the birds on each island received was later undisturbed by the inflow of alien genes.
