Nyāuli also known as Great Barbet, is an Asian barbet native to the Indian sub-continent and Southeast Asia, where it inhabits forests up to 3,000 m (9,800 ft) altitude.

Nyāuli has a blue head, large yellow bill, brown and green-streaked body, belly and a red vent. The plumage is green. It is the largest barbet species with a body length of 32–35 cm (13–14 in) and a weight of 192–295 g (6.8–10.4 oz).

The great barbet is a resident breeder in the lower-to-middle altitudes of the Himalayas, ranging across northern Pakistan, India, Nepal and Bhutan, Bangladesh and some parts of Southeast Asia, as far away as Laos.

The great barbet’s nesting season is from April to July. It typically builds nests in tree holes. Both male and females take care of the young. Its diet consists mainly of fruits and insects. The male’s territorial call is a very loud kay-oh. The alarm is a harsh keeab, and another call is a repetitive piou-piou-piou-piou.
