The Masked Colin is the first of the biack-throated species on our list. It is found 
within a restricted area in Southern Arizona, extending into Sonora, where Mr. Nelson 
states it occurs at from 1000 to 2500 feet above the sea °, 
According to Mr. Brown, the present species cannot be said to be a mountain bird, 
as it inhabits the “ mesas,” or tablelands, in the valleys of Arizona, and possibly the 
foot-hills+. He states that its food consists of seeds, berries, and insects, as well as 
green leaves. The same observer records that this Colin, besides the usual note of 
‘“‘ Bob-White,” has a second call, frequently heard when the flock is scattered, and used 
as an assembly-signal. The nest is a shallow depression in the ground, and the eggs 
are white 4.

This black-throated species is very nearly allied to O. ridgwayi, but is darker and of 
a deeper chestnut beneath. ‘The distinct white eyebrow is also another characteristic. 
The female, too, is much darker than that of O. ridgwayi, and the bars on the under 
surface are more complete and darker, but not to the same extent as in the femule 
of O. salvini,
