The greater flameback, or greater goldenback, is a large woodpecker, 33cm long, of typical woodpecker shape with an erect crest and a long neck. Colour varies between subspecies, but it always has an unmarked golden-yellow to dark brown back and wings, a red rump and a black tail. The underparts are white with dark markings, and the adult male always has a red crown (Wikipedia, general species account).
It nests in tree holes, laying three or four white eggs. A long tongue can be darted forward to extract wood-boring arthropod prey, and it drinks nectar too. In Malaysian mangrove forest it has been found to prefer tall Avicennia trees for foraging. The sources read give no range detail and do not name Bhutan.
