Adult female. Different from the male. Eufous, banded with 

 greyish black, the inner primaries and secondaries greyish white at 

 the tip ; quills black, barred with rufous on the inner web, the 

 inner secondaries uniform with the back ; tail deep cinnamon, 

 crossed with black bars, the tip whitish, the outer feather much 

 paler, the bars narrower and not continuous on the outer web, which 

 has only obsolete dark indications of them ; crown rufous, with 

 blackish shaft-streaks, the forehead and feathers encircling the 

 crown dull slaty blue ; facial features as in the male ; throat white ; 

 under surface of body fulvous, the abdomen and under tail-coverts 

 unspotted, the breast mottled with dull brownish cinnamon, the

 wing-coverts mottled like the breast. Total length 11"2 inches, 

 culmen 0-65, wing 7*9, tail 5'5, tarsus 1*45. 



Younger males have more bars on the upper surface, the remains 

 of their immature dress, which resembles the old female. Con- 

 siderable difference exists in the shade of the cinnamon back, this 

 colour appearing to me to fade from exposure.
