Grey-capped Pygmy Woodpecker

The grey-capped pygmy woodpecker is a small, dark woodpecker with dark eyes. It is barred black and white above, usually with unbarred central tail feathers, and has a dark buff underside with prominent dark streaking. The crown is dark grey, with a red nape in males, and strong black eye stripes and thin dark moustaches contrast with broad white eyebrows and cheeks (Wikipedia, general species account).

Its range extends from the Himalayas and Manchuria to Southeast Asia, in subtropical or tropical moist lowland, mangrove and montane forest. One subspecies is found mainly in Manchuria, eastern Siberia and Korea. The short source read does not name Bhutan and gives no size, diet or breeding detail, so none is stated.
