prefume, depend on the age of the bird; but one circumftance has 
been noticed in adult fpecimens that deferves particular notice, 
the vent and thighs, which are generally ferruginous or rufous, are 
fometimes white. Mr. Latham, fpeaking of this variation, fays he 
has a fpecimen, in which the thighs are dufky white, longitudinally 
marked with brown; and the vent of a plain white: one of our 
fpecimens alfo precifely agrees with this account. 
The length of the male bird is twelve inches, breadth two feet and 
three inches, weight feven ounces: the female is larger.
