context_page_description: The jungle myna is a myna, a member of the starling family. It is found patchily distributed across much of the mainland of the Indian Subcontinent but absent in the arid zones of India. It is easily recognized by the tuft of feathers on its forehead that form a frontal crest, a feature also found in the closely related Javan myna and the pale-bellied myna which were treated as a subspecies in the past. The eyes are pale, yellow or blue depending on the population and the base of the orange-yellow bill is dark. It has also been introduced either intentionally or accidentally into many other parts of the world including Fiji, Taiwan, the Andaman Islands, and parts of Japan. The species has also spread out on its own to some islands in the Pacific.
context_section_description: Jungle mynas are 23-centimetre (9.1 in) long and have grey plumage, darker on the head and wings. The sexes are indistinguishable in plumage. A large white wing patches on the base of the primaries becomes conspicuous in flight, and the tail feathers are broadly tipped in white. There is a tuft of feathers on the forehead arising at the base of the bill. The bill and legs are bright yellow, and there is no bare skin around eye as in the common myna and the bank myna. The base of the beak is dark in adults with a shade of blue at the base of the lower mandible. The southern Indian population has a blue iris. The northeastern Indian populations have a smoky dark belly and vent. Juveniles are browner with a pale throat and along the median of the underside.
  Abnormal leucistic plumages have been recorded.
  The calls of the jungle myna are higher pitched than those of the common myna. Foraging flocks make clipped cheeping contact calls.
  The jungle myna is part of the Acridotheres clade which is thought to have speciated in the late Pliocene and Pleistocene Periods. Unlike the starlings in the genus Sturnus, they do not have well-developed adaptations including the musculature required for prying or open bill probing (which need muscles to open the beak apart forcefully). The nominate population A. f. fuscus was described from Bengal by Wagler as Pastor fuscus in 1827. It has a pale creamy vent. This population with a yellow iris extends south of the Brahmaputra into Burma and the Malay Peninsula. A. f. fumidus of eastern India, mainly east of the Brahmaputra in Assam and Nagaland (although movements are known), was described by Sidney Dillon Ripley in 1950, although he placed it as a subspecies of cristatellus based on the prevailing treatment of the time. It has a darker smoky grey vent and can appear similar to the syntopic great myna, but the latter is darker and does not have a pale iris.. The peninsular Indian population mahrattensis described by W.H. Sykes in 1832 is identifiable by the blue iris. The population in the Malay Peninsula, torquatus, was described by W.R. Davison in 1892. It has a white throat and a half-collar extending around the neck. The species has a diploid chromosome number of 74 (80 in the common myna).
