Grey treepie

Appearance

It is the same size as other ''Dendrocitta'' species and is separated from them by the overall grey colour of the body. The races in the western part of the distribution have a greyish rump and some grey in tail while the eastern forms have a white rump and a black tail. The face and throat are dark and black with a diffuse mask. The body is grey on the underside becoming whiter towards the vent. The back and scapulars are brownish. The crown and nape are greyish and the black wing has a prominent white carpal patch. The vent is rufous and the outer tail feathers and tips of the central feathers are black.

The species occupies a large geographical range and has several recognised regional forms that differ slightly from one another for instance in colour and tail length. These include ''occidentalis'' of the western Himalayan foothills , ''himalayana'' from the central Himalayas east into Thailand and Vietnam. A disjunct population, said to have a smaller or narrower bill, is found in the Eastern Ghats of peninsular India, ''sarkari'', that is sometimes subsumed into ''himalayana''. The Southeast Asian races include ''assimilis'', ''sapiens'', ''sinica'', ''formosae'' and ''insulae'' .

It has been suggested that this species forms a superspecies along with ''Dendrocitta occipitalis'' and ''Dendrocitta cinerascens''.

Distribution

The grey treepie is largely arboreal and is found in a wide range of habitats including forest, cultivation and human habitation. The distribution range includes India, Nepal, Assam, Burma, Thailand, southern Tibet, Taiwan and Indochina.

Behavior

This treepie is mostly an arboreal feeder but will take some food from the ground, especially in cultivated regions. A wide range of insects and other invertebrates are taken including berries, nectar, grain and other seeds and also small reptiles, eggs and nestlings. It sometimes joins mixed-species foraging flocks.

In the foothills of the Himalayas in India, they are known to breed from 2000 to 6000 feet high mainly during the months of May to July. The nest is a shallow cup lined with hair and is built in trees and bushes or clumps of bamboo with 3-4 eggs per clutch.

The voice is described as harsh and grating, but like other species is quite varied and includes a grating k-r-r-r-r sound as well as more melodious notes not unlike those of the rufous treepie. These include a ''tiddly-aye-kok'', ''ko-ku-la'' and barking ''braap...braap...braap'' calls.
