Adult Male-—Top of the head and nape dark chestnut ; upper 
parts olive-brown, with a rufous tinge in freshly-moulted 
specimens; sides of head and fore-neck chestnut; breast 
brownish or olivaceous-grey ; belly paler. Total length, 23 
inches; wing, 8°3; tail, 10°3; tarsus, 2°7; middle toe and 
claw, 2°4. 
Adult Female-—Probably similar to the male, but I have not 
examined any examples in which the sex has been properly 
ascertained. 
Range.—Northern South America ; Cayenne, British Guiana, 
Rio Negro, and Rio Branco. 
Habits—According to Mr. C. B. Brown the native name of 
this bird is ‘‘Nanaquah.” It is easily tamed, readily inter- 
breeds with domestic fowls, and the hybrids are said to be very 
pugnacious. Its native name is, of course, derived from its cry 
—of ‘ Nannaquoi.”
