Both the adults are much worn, and the female has a tinge 

 of chestnut on the back, 



" Irides bright yellow ; bill, legs, and toes pale slate- 

 coloured, upper mandible darker.^^ 



The young are similar, exceptiog 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.
