The blue-bearded bee-eater is probably the largest of the bee-eaters, 31 to 35cm long and weighing 70 to 93g. It has a large sickle-shaped bill and a square-ended tail that lacks the typical 'wires' of the smaller bee-eaters. The belly is yellowish to olive with streaks of green or blue. It is found in much of the Indian subcontinent and parts of Southeast Asia, in forest clearings (Wikipedia, general species account).
It has a loud call but is not as gregarious or active as the smaller bee-eaters, and is found singly or in small groups of up to three, patchily distributed. Calls include a hornbill-like cackle, a dry 'kit-tik' in a series and a hollow nasal 'kyao'. The nest is a deep tunnel in a mud bank with four spherical white eggs. The sources read do not name Bhutan.
