FAMILY PERDICIDvE 



An inhabitant of partly open places as well 

 as of the forest, often seen in tall trees or on or 

 near the ground. A common name of this con- 

 spicuously crested, long-tailed bird is derived 

 from its call, chiefly heard in the early morning 

 and evening, a harsh and far reaching reiteration 

 of chacalaca, chacalaca. 



3. Family PERDICID^) 

 The Quails and Partridges 



These are more or less completely terrestrial, 

 stout-bodied, rather short-legged birds closely 

 related to the grouse and pheasants, but of a 

 smaller size and having a short tail. The bill 

 is very short, the head often crested, the wings 

 rounded, the plumage usually handsomely 

 variegated but lacking in brilliant colors. 



The quails mostly frequent brushy or more 

 or less open localities, feeding on seeds and 

 insects and nesting on the ground. They 

 lay numerous eggs and the brood often re- 

 mains together in a flock until the following 

 year. Though they fly swiftly, they are good 

 runners and often prefer to make their escape 

 on foot.
