The large-billed crow is 46 to 59cm long and weighs 450 to 1,000g. The largest subspecies has a bill measuring 70 to 80mm and the smallest 52 to 67mm. There are normally three to five eggs, incubated for 17 to 19 days, and the egg is a broad oval, rather pointed at the smaller end (Wikipedia, general species account).
The only source read for the Bhutan guide gives these measurements and egg details. No plumage, range, habitat or diet information was found, so none is stated.
