The crested honey buzzard is a fairly large raptor about 57 to 60cm long, weighing 750 to 1,490g. It prefers well-forested areas with open spaces and is found from sea level up to about 1,500m, occasionally up to 1,800m (Wikipedia, general species account).
During migration it goes above 3,000m. The sources read for the Bhutan guide give these figures only. No plumage, range, diet or breeding information was found, so none is stated, and its occurrence in Bhutan is flagged for checking.
