The
ruby-cheeked sunbird (
Chalcoparia singalensis) is a species of sunbird in the family Nectariniidae.
Taxonomy: The ruby-cheeked sunbird was formally described in 1789 by the German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus´s
Systema Naturae. He placed it with the wagtails in the genus
Motacilla and coined the binomial name
Motacilla singalensis. Gmelin erroneously specified the type locality as Ceylon (now Sri Lanka) where the species does not occur. The locality was designated as Malacca on the Malay Peninsula by the American ornithologist Harry C. Oberholser in 1912. Gmelin based his account on the "green warbler" from the East Indies that had been described and illustrated in 1776 by the English naturalist Peter Brown. The ruby-cheeked sunbird is now the only species placed in the genus
Chalcoparia that was introduced in 1850 by the German ornithologist Jean Cabanis. The genus name is from Ancient Greek
khalkoparēos meaning "with cheeks of bronze". The specific epithet is from the erroneous type locality, Sri Lanka.
