eight inches in height, and, when the lengthened 
feathers, which most of them possess on the throat, 
or sides of the jaw, are raised, they have a very hold 
and commanding appearance. The head, neck, and 
upper part of the hreast, are hluish-grey, darker on 
the crown, vrhich is often marked with a streak 
of brownish-black ; the chin and long maxillary 
feathers of a paler grey ; the tint of the neck and 
breast shades nearly into pure white on the belly, 
vent, and lower tail-covers; the lower part of 
the hack of the neck, the hack, rump, shoulders, 
and scapulars, are reddish-orange ; the feathers 
crossed with entire and interrupted bars of black ; 
the greater covers greyish-white ; secondaries deep 
brownish-black ; quills very powerful, the first nar- 
row and acuminated, the others with the outer web 
suddenly broadening at about a third from the base, 
these wood-brown, becoming brownish-black at the 
tips ; the central feathers of the tail are reddish- 
orange with white tips, and. a black bar crossing at 
about an inch from the extremity, with another 
narrower towards the base. The more exterior 
feathers are greyish-white nearly pure at. the base, 
and slightly tinted with the reddish-orange near the 
black bar.
