Distribución y hábitat

The green cochoa is found in Cambodia, China, India, Laos, Myanmar, Nepal, Thailand, Vietnam, and possibly Bhutan. Its natural habitats are subtropical or tropical moist lowland forests and subtropical or tropical moist montane forests. They make seasonal movements that are not well understood. Their distribution in winter in India is unclear as the species is found only in summer. An old record from Uttaranchal (Nainital) is the westernmost record, and no recent records exist from Nepal. Most records are east of northwest Bengal.

Comportamiento

The green cochoa is usually seen in pairs or small groups sitting in tall trees. They usually feed close to the ground, on mollusks, insects and berries. They sometimes launch aerial sallies to capture insects. This species breeds in summer, and the nest is much like that of the purple cochoa, but is usually placed close to water. Both parents take turns incubating. The song is a thin and clear feeeee that dies away. Calls include a short high-pitched pok and harsh notes.<p>The glossy eggs are ellipsoidal and densely speckled.
