Adult female. Different from the male. General colour 
above tawny brown, duller on the head, inclining to foxy 
chestnut on the upper tail-coverts j the tail chestnut-red; 
wing-coverts dull brown, edged with tawny brown, so that

female, the breast being bright orange as well as the flanks.

name of rufifrons, as, when adult, the forehead is brilliant 
blue, and the type of C. rufifrons in the British Museum 
shows that the species is founded on a male which has gained 
almost perfect plumage but still retains the rufous eyelid and
