The velvet-fronted nuthatch is a small nuthatch, 12 to 13.5cm long. Three to six eggs are laid, white speckled with red. The female spends more time incubating, but both parents take turns feeding the young (Wikipedia, general species account).
That is all the source read for the Bhutan guide gives. No plumage, range, habitat or diet information was found, so none is stated, and its occurrence in Bhutan is flagged for checking.
