Adult. Head and neck broccoli brown, marked with dark shaft-streaks; chin, upper 
throat and ear-coverts whitish with dark shaft-streaks; rest of upper surface 
sepia brown, the feathers margined (on the wing-coverts strongly waslied) with the 
colour of the head; tail — in young specimens plainly, in old specimens indistinctly 
— crossed with numerous dusky bars; under surface bistre brown with dark shaft- 
streaks, darkest on the under wing-coverts and lightest on the under tail-coverts and 
thighs, longest under wing-coverts grey-brown, with dark bars; primaries black, 
washed and mottled with pale brown towards the base of the wing, whitish at the 
concealed base of the outer quills (2, S. Celebes 26. 1. 78: Platen, C 11110, and others). 
“Iris brown; cere light yellow; bill black; feet citron-yellow” (Platen a 13). 
Younger birds have a more mottled appearance than those fully adult, owing to the pale 
margins of the feathers being more distinct and the banding of the tail strongly ex- 
pressed.

Eggs. Australia; 3; dull white ground-colour, with reddish irregular spots and dots: mean 
of two measured 45.5 mm X 37.8 (North a XIV). Biu-mah; usually 3; egg-lining 
bright green; shell tolerably smooth and glossless, dull white, marked and blotched 
with rust colour, bright in the majority, but pale in a few. Average of 12 eggs. 
53 X 41.4 mm (Oates 15). 
It would thus appear that the Austrahan bird usually lays a consicera y 
smaller egg.

of twigs, etc. situated in a tree.
