The jungle crow (Corvus macrorhynchos), is a widespread Asian species of crow. It is very adaptable and is able to survive on a wide range of food sources, making it capable of colonizing new areas, due to which it is often considered a nuisance, especially on islands. It has a large bill which is the source of its scientific name macrorhynchos (Ancient Greek for "large beak"), and it is sometimes known by the common names large-billed crow or thick-billed crow. It can also be mistaken for a raven. Johann Georg Wagler first described the species from a holotype obtained from Java in the year 1827
It has 11 subspecies, and some of these are distinctive vocally, morphologically and genetically, leading to treatments that raise several of these to species status.
The overall size (length: 46–59 cm; 18–23 in.) and body proportions vary regionally. In the far northeast in Japan, the Kuriles and the Sakhalin peninsula, it is somewhat larger than the carrion crow, while the taxon from India in the southwest of its range is appreciably smaller than the carrion crow. All taxa have a relatively long bill with the upper one quite thick and arched, making it look heavy and almost raven-like. Generally, all taxa have dark greyish plumage from the back of the head, neck, shoulders and lower body. Their wings, tail, face and throat are glossy black. The depth of the grey shading varies across its range to almost black in the Indian taxon.
The range of this species is extensive and stretches from the northeastern Asian seaboard to Afghanistan and eastern Iran in the west, through South and Southeast Asia, to the Lesser Sundas and Cambodia in the southeast. It occurs in woodland, parks and gardens, cultivated regions with at least some trees, but is a bird of more open country in the south of its range where it is not in competition with the raven and carrion crow of the north.
