This coucal is slightly smaller than the more common Greater Coucal from which it can be readily distinguished by its large pale-green bill.  The wings are darker chestnut than the Greater Coucal’s.  Has a purple sheen on the head and neck.  Sexes alike.  A rare forest loving bird that inhabits the dense under growth of wetzone forests with dwarf bamboo.  Does not hesitate to come in to home gardens adjacent to these forests.  Very elusive.  Lives in pairs.
