to the size of a pinhead. The second was similarly 
provided, but contained, in lieu of mustard seed, a 
grasshopper fully an inch in length. These two were 
taken on the mesa. The third, from a bird taken in 
the valley, contained about twenty medium-sized red 
ants, several crescent-shaped seeds, and a large num- 
ber of small, fleshy green leaves.” 
Mr. Brown pointed out, years ago, that the intro- 
duction of live-stock into southern Arizona bade fair 
to exterminate the masked bobwhite in that territory, 
by the destruction of its nests and eggs by horses and 
cattle, as well as by the eating of the cover among 
which it lives. His prediction has been verified, and 
as recently as June, 1909, he wrote, saying: “Colinus 
ridgwayt is a dead bird so far as Arizona is, as yet, con- 
cerned, but it is again getting a good foothold in So- 
nora, about 75 miles south of the line. I am almost 
afraid to say anything about it, however, as I fear I 
might send skin hunters into the country.” 
Other writers have noted in our common bobwhite 
the same tendency to disappear in sections where gen- 
eral farming has given place to stock-raising. 
The bobwhite family attains its greatest development 
in Mexico. Though differing greatly in color, the pat- 
tern of that color is somewhat similar in all the differ- 
ent forms. Several are black, or black mottled with 
white, on the breast and tail, where our bird is pale in 
color, just freckled with black. All have the same 
whistle with which we are so familiar in our own bird,
