The common moorhen is a medium to large rail, 30 to 38cm long with a wingspan of 50 to 62cm. Body mass ranges from 192 to 500g. About eight eggs are usually laid per female early in the season, while a brood later in the year usually has only five to eight or fewer. Incubation lasts about three weeks (Wikipedia, general species account).
The only source read for the Bhutan guide gives these measurements and breeding details. No plumage, habitat, diet or range information was found, so none is stated, and the entry is kept short.
