Open encyclopedia reference
The azure dollarbird (Eurystomus azureus) also known as the azure roller, purple dollarbird or purple roller, is a species of bird in the family Coraciidae. It is endemic to North Maluku in Indonesia. Formerly, some authorities considered the azure dollarbird to be a subspecies of the oriental dollarbird.
A molecular phylogenetic study by Ulf Johansson and collaborators published in 2018 found that the azure dollarbird was nested in a clade containing subspecies of the Oriental dollarbird (Eurystomus orientalis).

Origins, evidence & remaining research
Name authority and publication references document nomenclature where the source supplies it. They do not establish evolutionary origins or the earliest fossil occurrence.
Specimen-level evidence, morphology, ecological research, phylogenetic studies, a comprehensive bibliography and a located literary passage have not yet been compiled for this record. A suitable sourced image remains to be added.
