QUAIL.

Notes on the Rui'Fed Grouse. The young of this species acquire the Avings quite rapidly and fly 

 wKen only a few days old whereas the young Quails of the same age are entirely without wing quills and 

 .consequently cannot fly at all at this early age. Compare fig. 45 where I figure a young Grouse about ten 

 day;j old with fig. 4ii which is a figure of a Yotmg Quail of the same age.
