Sulawesi Crow

It was formerly considered as conspecific with the Sunda crow with the combined taxa known as the slender-billed crow. The Sulawesi crow was formally described in 1936 by the German ornithologist Erwin Stresemann based on a specimen collected near the village of Rurukan in northern Celebes (now Sulawesi). He considered the specimen to be a subspecies of the Sunda crow and coined the trinomial name Corvus enca celebensis. (Wikipedia, general species account).

Sulawesi Crow is a passerine bird in the crow family Corvidae that is endemic to the Indonesian island of Sulawesi. It is now separated as a distinct species based on vocal and genetic differences. With the split the name of Corvus enca was changed from "slender-billed crow" to "Sunda crow". Two subspecies are recognised: Corvus celebensis celebensis Stresemann, 1936 – Sulawesi and satellites Corvus celebensis mangoli Vaurie, 1958 – Sula Islands (east of Sulawesi) (Wikipedia, general species account).
