Both the adults are much worn, and the female has a tinge 
of chestnut on the back.

coloured, upper mandible darker/"’ 
The young are similar, excepting that the December bird 
has a paler throat, is brighter on the breast and flanks, and 
has a darker bill. They differ from the adults as follows :— 
“ Above dull russet-brown, crown dull chestnut; beneath 
pale creamy white, breast and flanks slightly washed with 
reddish brown; edges of secondaries russet-brown. 
“ Irides dark blue-grey; bill dark horn-coloured, greater 
part of lower mandible and gape pale yellow ; legs and toes 
ashy.” 
A fairly common species which inhabits rough grass¬ 
lands and the canadons ; it has a whistling call. 
The nest is usually placed in a low solitary tree or shrub, 
and is a longish structure of sticks placed almost horizon¬ 
tally, the entrance being at the higher end with a tunnel 
communicating with the nesting cavity ; it is lined with wool 
and hair.
