Common Hill Myna, Gracula religiosa

The Common Hill Myna (Gracula religiosa), sometimes spelled “mynah” and formerly simply known as hill myna, is the myna most commonly seen in aviculture, where it is often simply referred to by the latter two names. It is a member of the starling family (Sturnidae), resident in hill regions of South Asia and Southeast Asia.

The Sri Lanka hill myna, a former subspecies of G. religiosa, is now generally accepted as a separate species G. ptilogenys. The Enggano hill myna (G. enganensis) and Nias hill myna (G. robusta) are also widely accepted as specifically distinct, and many authors favor treating the Southern hill myna (G. indica) from the Nilgiris and elsewhere in the Western Ghats of India as a separate species.

Distribution and ecology
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 2000 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 hole in a tree. The usual clutch is two or three eggs.

Description
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 and Enggano hill mynas differ in details of the facial wattles, and size, particularly that of the bill.

Sexes are similar; juveniles have a duller bill.

With the Southern, Nias and Enggano hill mynas as separate species, the Common Hill Myna, Gracula religiosa, has seven or eight subspecies which differ only slightly. They are:

• Gracula religiosa andamanensis Beavan 1867 – Andaman hill myna, Andaman Islands, central (Nancowry) group of the Nicobar Islands

• Gracula religiosa batuensis – Batu and Mentawai Islands

• Gracula religiosa halibrecta Oberholser 1926 – Great Nicobar hill myna, Great Nicobar Little Nicobar and adjacent islets in the Nicobar Islands, Doubtfully distinct from Gracula religiosa andamanensis.

• Gracula religiosa intermedia – northwestern Indochina and adjacent northeastern India and southern China

• Gracula religiosa palawanensis – Palawan in the Philippines

• Gracula religiosa peninsularis – Bastar hill mynah, central India, (State Bird of Chhattisgarh, India)

• Gracula religiosa religiosa – Greater Sundas (except Sulawesi) and Peninsular Malaysia

• Gracula religiosa venerata – western Lesser Sundas

Vocalisations
The Common Hill Myna is often detected by its loud, shrill, descending whistles followed by other calls. It is most vocal at dawn and dusk, when it is found in small groups in forest clearings high in the canopy.

Both sexes can produce an extraordinarily wide range of loud calls – whistles, wails, screeches, and gurgles, sometimes melodious and often very human-like in quality. Each individual has a repertoire of three to 13 such call types, which may be shared with some near neighbours of the same sex, being learned when young. Dialects change rapidly with distance, such that birds living more than 15 km apart have no call-types in common with one another.

Unlike some other birds, such as the Greater Racket-tailed Drongo (Dicrurus paradiseus), the Common Hill Myna does not imitate other birds in the wild, although it is a widely held misconception that they do. On the other hand, in captivity, they are among the most renowned mimics, perhaps on par only with the African grey parrot (Psittacus erithacus). They can learn to reproduce many everyday sounds, particularly the human voice, and even whistled tunes, with astonishing accuracy and clarity.

Remarks from the Recordist

Bird watching at Botanical Garden in Kolkata. A fantastic place for birding. I heard the Common Hill Myna, unknown to me then and it was a fantastic sound. I could only hear the bird but I went in to the bushes and I found the bird after much searching.

Back at the hotel and I found out that it was a Common Hill Myna on the internet



Remarks from the Recordist

Recorded with my ZOOM H5 Handy recorder. High filter pass with Audacity

2 short recordings of the same birds put together to make it longer

PLEASE! The birds was high up in a tree and I took the picture for identifying purpose ONLY! So 3 steps over exposure just to see the colours of the bird against the light

Recordings of this species are currently restricted.

Why are recordings of certain species restricted?
Some species are under extreme pressure due to trapping or harassment. The open availability of high-quality recordings of these species can make the problems even worse. For this reason, streaming and downloading of these recordings is disabled. Recordists are still free to share them on xeno-canto, but they will have to approve access to these recordings.

We do not take this action lightly, and we wish it were not necessary, but we have been convinced that the negative impacts of offering easy access to these recordings outweigh the benefits. If you would like access to these recordings, you may contact the recordist directly.

Pet trade and conservation
The hill mynas are popular cage birds, renowned for their ability to imitate speech. The widely distributed Common Hill Myna is the one most frequently seen in aviculture. Demand outstrips captive breeding capacity, so they are rarely found in pet stores and usually purchased directly from breeders or importers who can certify the birds are traded legally.

This species is widely distributed and locally common, and if adult stocks are safeguarded, it is able to multiply quickly. On a worldwide scale, the IUCN thus considers the Common Hill Myna a Species of Least Concern. But in the 1990s, nearly 20,000 wild-caught birds, mostly adults and juveniles, were brought into trade each year.

In the central part of its range, Gracula religiosa intermedia populations have declined markedly, especially in Thailand, which supplied much of the thriving Western market.

Its neighbor countries, from where exports were often limited due to political or military reasons, nevertheless supplied a burgeoning domestic demand, and demand in the entire region continues to be very high. In 1992, Thailand had the Common Hill Myna put on CITES Appendix III, to safeguard its stocks against collapsing.

In 1997, at the request of the Netherlands and the Philippines, the species was uplisted to CITES Appendix II. The Andaman and Nicobar Islands subspecies Gracula religiosa andamanensis and (if valid) Gracula religiosa halibrecta, described as “exceedingly common” in 1874, qualified as Near Threatened in 1991. The former is not at all common anymore in the Nicobar Islands and the latter—if distinct—has a very limited range.

Elsewhere, such as on the Philippines and in Laos, the decline has been more localized. It is also becoming increasingly rare in regions of northeastern India due to capture of fledged birds for the illegal pet trade. In the Garo Hills region, however, the locals make artificial nests of a split-bamboo framework covered with grass, and put them up in accessible positions in tall trees in a forest clearing or at the edge of a small village to entice the mynas to breed there.

The villagers are thus able to extract the young at the proper time for easy hand-rearing, making Common Hill Myna farming a profitable, small-scale cottage industry. It helps to preserve the environment, because the breeding birds are not removed from the population, while habitat destruction is curtailed because the mynas will desert areas of extensive logging and prefer more natural forest to plantations.

As the mynas can be something of a pest of fruit trees when too numerous, an additional benefit to the locals is the inexpensive means of controlling the myna population: failing stocks can be bolstered by putting out more nests than can be harvested, while the maximum proportion of nestlings are taken when the population becomes too large.
