Description—Adult male. Differs from insignis in having the back 
and wings an olive-brown with little or no gloss, and no tint of copper; in 
having the rump darker and sometimes tinged with olive; in having the 
terminal pale band on the tail much narrower, hardly one-quarter of the total 
length of the tail, and in having the under-surface darker and more vinous, 
and much mixed with ochre on the abdomen and posterior flanks. The 
under tail-coverts are often more or less faintly freckled with dusky, and 
the axillaries and under aspect of the wing are much darker than in either 
insignis or griseicapilla. As a rule, also, the white of the chin and throat 
is much more restricted in area. 
Colours of soft parts. ‘‘ Bill dull lake-red at the base, slaty at the tip ; 
orbits lake-red, irides red-brown ; legs dull lake-red ” (Jerdon). 
Measurements. Length 16 to 18 in. ( = 396.4 to 447 mm.) ; wing 8.3 to 
9.2 in. (= 210.8 to 233.6 mm.) ; tail about 7in. (= 177 mm.) ; bill at front 
about .98 ( = 24.9 mm.), and from gape about 1.4 in. ( = 26.5 mm.) ; tarsus 
about 1 in. ( = 25.4 mm.). 
Adult female. Does not differ from the male, except in being very 
slightly smaller on an average, with a wing of about 8.5 in. ( = 215.9 mm.). 
Distribution. Southern India as far north as the Kanara district in 
the Bombay Presidency on the west, where Davison records it as common. 
Throughout the mountainous regions of Koorg, Wynaad, and Neilgherries, 
but apparently not in the east of the Madras Presidency. It has been recorded 
from the hills east of Mysore which run southwards from Bangalore to the 
Neilgherries, but has not yet been recorded from further east than this.
