Females, at least in some species, seem to betray immaturity by 



having their rufous plumage traversed by dark irregular striae and 



by the white markings of the adult being ill-defined and not pure in 



colour ; males by having the white nuchal aud gular collar-plumes 



indistinct, undeveloped, and sullied by tawny. Some importance has 



been attached to the fact that in occasional examples of the genus the 



maxilla is found to overlap the mandibula. But this appearance 



seems to be owing to the imperfect preparation of the skin.
