Common Hill Myna

This is a stocky jet-black myna, with bright orange-yellow patches of naked skin and fleshy wattles on the side of its head and nape. At about 29 cm length, it is somewhat larger than the common myna (Acridotheres tristis). It is overall green-glossed black plumage, purple-tinged on the head and neck. Its large, white wing patches are obvious in flight, but mostly covered when the bird is sitting. The bill and strong legs are bright yellow, and there are yellow wattles on the nape and under the eye. These differ conspicuously in shape from the naked eye-patch of the common myna and bank myna (A. ginginianus), and more subtly vary between the different hill mynas from South Asia: in the common hill myna, they extend from the eye to the nape, where they join, while the Sri Lanka hill myna has a single wattle across the nape and extending a bit towards the eyes. In the southern hill myna, the wattles are separate and curve towards the top of the head. The Nias myna differs in details of the facial wattles, and size, particularly that of the bill. Sexes are similar; juveniles have a duller bill. The subspecies differ in size, in the pattern of wattles on the head and in the glossiness of the plumage.

This myna is a resident breeder from Kumaon division in India (80° E longitude) east through Nepal, Sikkim, Bhutan and Arunachal Pradesh, the lower Himalayas, terai and foothills up to 2,000 m ASL. Its range continues east through Southeast Asia northeastwards to southern China, and via Thailand southeastwards across northern Indonesia to Palawan in the Philippines. It is virtually extinct in Bangladesh due to habitat destruction and overexploitation for the pet trade. A feral population on Christmas Island has likewise disappeared. Introduced populations exist in Saint Helena, Puerto Rico and perhaps in the mainland United States and possibly elsewhere; feral birds require at least a warm subtropical climate to persist. This myna is almost entirely arboreal, moving in large, noisy groups of half a dozen or so, in tree-tops at the edge of the forest. It hops sideways along the branch, unlike the characteristic jaunty walk of other mynas. Like most starlings, the hill myna is fairly omnivorous, eating fruit, nectar and insects. They build a nest in a tree hole. The usual clutch consists of two or three eggs. There is no sexual dimorphism, which limits the selection of potential mates.

Pet trade and conservation. The hill mynas are popular cage birds, well known for their ability to imitate speech. …
