20 GAME BIRDS OF NORTH AMERICA. 
the Great Salt Lake Valley, Utah, and are now common 
in various portions of that State. In 1875 a few were liber- 
ated at Boisé City, Idaho, and not many years after the 
birds were numerous along the Boisé River and west of 
the Snake River. It has also been introduced into Colo- 
rado, California, quite abundant about Gilroy, Oregon, 
in several of the islands in Puget Sound, and wherever 
the climate is suitable and food abundant. This species 
will flourish and increase in numbers in most climates, 
soon adapting itself to its surroundings. As a rule, 
Bob White is a resident and passes his life in or near 
the places in which he was hatched, but in the more 
northern portions of his habitat, even as far south as 
Virginia, there appears to be a partial migration north 
and south in the spring and autumn, and when shoot- 
ing I have often met with coveys that seemed to be 
traveling, though of course it is difficult to prove the 
fact. But it is certain that within a district where every 
covey which inhabits it is known and the place it usually 
frequents well ascertained, occasionally in the autumn 
other bevies will appear upon the same ground, appar- 
ently on the tramp, and which make no stay. 
This bird never goes in packs or large flocks, like the 
plumed quails of New Mexico, Arizona, or California, 
but individuals of each covey, presumably one family, 
remain together, and even after they have been decimated 
by the sportsman or by furred and feathered enemies, 
the survivors rarely join another bevy, but keep by 
themselves until the recurring spring. The mating 
season commences according to the latitude of the birds’ 
habitat, from March to May, and nidification from April 
to June. As spring begins to temper the keen blasts of 
winter, and the rays of the returning sun, coming from 
the southern limit of its journey below the Equator, cause
