faded.

Irides clear pale yellow ; bill pale green. 
The January and February birds are moulting, the old 
feathers being much worn. Both the males are whiter below 
and less marked than the females. 
This bird was exceedingly plentiful in the Ajo district, 
and was very tame. The excellent notes on its habits given 
by Hudson need no farther additions. 
The nesting-hole is usually made in sandy soil and is 
about three or four feet long : it is sometimes curved, more 
often straight, and never far below the surface of the ground, 
the end of the burrow being circular. Five or six eggs 
constitute the clutch. Most of the females secured were 
caught on the eggs, and offered no resistance when captured. 
Thirty-nine eggs were brought home, taken at Ajo between 
October 22nd and November 1st, 1909, and 
axis 1*35 to 
5 m., 
diam. 1 05 to 1*15.
