Oriental Dollarbird (Eurystomus orientalis)
French: Rolle oriental German: Türkisracke Spanish: Carraca oriental
Other common names: Dollarbird, Asian Dollarbird
Taxonomy: Coracias orientalis Linnaeus, 1766, Java.
Closely related to E. azureus, with which sometimes treated as conspecific; breeding record of present species from Loloda Is (off NW Halmahera, and almost inside range of E. azureus) provides additional support for their treatment as two separate species. Taxonomy and nomenclature somewhat confused, especially for continental Asian forms: nominate and race calonyx intergrade in areas of S China and N Indochina, and intermediate birds from N Thailand sometimes accorded race deignani; proposed race latouchei from NE China considered inseparable from calonyx; cyanicollis is a synonym of nominate, abundus is synonym of calonyx; birds from S Sulawesi and Lesser Sundas, described as race connectens, appear intermediate between nominate and pacificus but variable, with some individuals inseparable from latter; in the past, birds of NW Australia occasionally separated as race bravi. Ten subspecies currently recognized.
