forty-odd species are known. In habits, they agree more or less completely with the well 
known Bob-white. Our species are apparently monogamous, and go in small flocks, called 
“‘eoveys,” usually consisting of the members of one family; they are terrestrial, but take to the 
trees on occasion; nest on the ground, laying numerous white or speckled eggs; are chiefly 
granivorous, but also feed on buds, soft fruits, and insects; and are non-migratory.

As all these genera have each but a single species in this country, excepting Lophortyx, the foregoing is 
nearly equivalent to a determination of the species. 
OR/TYX. (Gr. éprvé, ortux, a quail.) 
Feathers of crown lengthened and erec- 
tile, but hardly forming a true crest. 
Tail about 2 as long as the wing.
