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 〔(The Internet Bird Collection )〕 ==Subspecies== 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.〔Madge, S.
