 debted for much of the information contained in 

 the subsequent account of these orders. 



They generally associate in pairs, both sexes 

 assisting in incubation and feeding their young. 

 Their principal food consists of grain and seeds ; 

 they drink much, and not at intervals like other 

 birds, but by a continued draught : their note is 

 peculiarly soft and expressive, and is well distin- 

 guished from that of any other bird by its plain- 

 tive and mournful sound: they generally breed 

 more than once in the year ; the female lays two 

 eggs at a time, one of which generally produces a 

 male, the other a female. 



They are greatly dispersed over the old con- 

 tinent, but only two or three species occur in 

 America.
