Racket-tailed roller
species of bird
The racket-tailed roller (Coracias spatulatus) is a species of bird in the family Coraciidae. It is found in southern Africa from Angola, south-eastern Democratic Republic of Congo and southern Tanzania to northern Botswana, Zimbabwe, Malawi and Mozambique.
Taxonomy and systematics
The racket-tailed roller was formally described in 1880 by the naturalist Roland Trimen under its current binomial name Coracias spatulatus from a specimen collected near the Zambezi River in southern Africa. The specific epithet spatulatus is Modern Latin meaning "spatulate" or "spoon-shaped". The species is monotypic: no subspecies are recognised. A molecular phylogenetic study published in 2018 found that the racket-tailed roller was most closely related to the purple roller (Coracias naevius).
The phylogenetic relationships among the Coracias species are shown below, from the molecular study by Johansson et al. (2018)
Alternate names for the racket-tailed roller include the Angola racket-tailed roller and Weigall's roller.
Description
The racket-tailed roller is so named for the conspicuous elongated outer feathers on its tail which have long streamers ending in paddle-shaped tips. The bird is 28 to 30 cm (11 to 12 in) long with the streamers extending another 8 cm (3 in).

Why this record matters
A short description can identify a subject without explaining its stakes. For “Racket-tailed roller”, the useful work is to connect “species of bird” to the records capable of establishing context and consequence.
Stable identifiers, scientific names and standards terminology offer the best bridge between this overview and specialist evidence. The source revision retrieved here is dated Feb 19, 2026. The linked authority identifier is Q786566. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1880 and 2018.
Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
