The northern nutcracker is a dark brown, broad-winged, short-tailed crow-family bird, 32 to 38cm long with a wingspan of 49 to 53cm. It is slightly smaller than the Eurasian jay but with a much larger bill and a slimmer, crestless head. The plumage is mid-to-dark chocolate brown, heavily spotted with white on the face, neck, mantle and underparts, and the wings and tail are black with a greenish-blue gloss (Wikipedia, general species account).
Where pines are absent, the seeds of spruce and hazel nuts are an important part of the diet, and it avidly digs out bumble bee and wasp nests for the grubs. Nesting is always early, to make the best use of pine nuts stored the previous autumn, usually high in a conifer, with two to four eggs incubated for 18 days. The account opened does not name Bhutan.
