He considered the specimen to be a subspecies of the Sunda crow and coined the trinomial name Corvus enca celebensis. [1] [2] 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". [3] [4] Two subspecies are recognised: [3]

The largest corvids are the common raven (Corvus corax) and the thick-billed raven (Corvus crassirostris), both of which regularly exceed 1,400 grams (3.1 pounds) and 65 cm (26 in). Species can be identified based on size, shape, and geography; however, some, especially the Australian crows , are best identified by their raucous calls.
They considered the specimen to be a subspecies of the Slender-billed crow (now Sunda crow) and coined the trinomial name Corvus enca sierramadrensis. [2] It was then formerly treated as a subspecies of the Samar crow ( Corvus samarensis ) but is now separated as a distinct species based on vocal and morphological differences.
They are as follows: (a) The Philippines versions of the slender-billed crow, Corvus enca, are defined as two new species, small crow, Corvus samarensis, found in the main Philippines islands, and Palawan crow, Corvus pusillus, found on Palawan.
