Taxonomy and systematics

The purple-winged roller was formally described in 1819 by the French ornithologist Louis Pierre Vieillot under the binomial name Garrulus temminckii.^[2] The specific epithet was chosen to honour the Dutch ornithologist Coenraad Jacob Temminck.^[3] The type locality is the island of Sulawesi.^[4] The purple-winged roller is now one of nine species placed in the genus Coracias that was introduced by Carl Linnaeus in 1758.^[5][6] A molecular phylogenetic study published in 2018 found that the purple-winged roller was most closely related to the Indochinese roller (Coracias affinis).^[7]

The phylogenetic relationships among the Coracias species are shown below, from the molecular study by Johansson et al. (2018)^[7]

Alternate names for the purple-winged roller include the Celebes roller, Sulawesi roller, and Temminck's roller.

Description

The purple-winged roller is 30–34 cm (12–13 in) in length, similar in size to the Eurasian jay. The cap and upper-tail coverts are bright azure blue, the back is dark-olive, with the rest of the plumage mainly dark blue. The large bill is black. The sexes are alike. Juveniles are similar to the adults but with duller plumage.^[8]
