A range of short brown stiff feathers, about six inches long, fixed in the _uropygium_, is the real tail, and serves as the fulcrum to prop the train, which is long and top-heavy, when set on end.
The crown of the head, the throat, the ear-coverts, and the eyes have usually distinct tints in all highly coloured birds; the region of the furcula has often a distinct patch of colour, as have the pectoral muscles, the uropygium or root of the tail, and the under tail-coverts. [
