Greater Yellownape

The greater yellownape is a large, olive-green woodpecker with a prominent yellow-crested nape and throat. It is dark olive green above with grey underparts, a brownish crown and chestnut flight feathers barred with black, and the bill often looks whitish. It is found from northern and eastern India to south-eastern China, Indochina, Hainan and Sumatra (Wikipedia, general species account).

Its natural habitat is subtropical or tropical moist lowland and montane forest. The short source read gives no size, diet, voice or breeding detail, and does not name Bhutan, so none is stated, and its occurrence there is flagged for checking.
