214 KET AND DESCRIPTION 



ORDER VII. PIGEONS, ETC. (COLUMB./B) 



An order represented, in our region, only by the following : 



FAMILY XXXI. PIGEONS (COLtTMBID^) 



This large family (300 species) of land birds, found in the 

 warmer regions of all portions of the earth, is represented in 

 the eastern United States by but few species, only four being 

 found north of southern Texas and southern Florida. They 

 cannot be said to frequent any particular kind of haunt ; 

 many live most of the time on the ground, some are tree 

 birds, some seek open places, while others are to be found 

 only in forests. They are short-billed, small, round-headed, 

 plump-bodied, short-legged, smooth-plumaged birds, with a 

 peculiar, more or less iridescent, grayish and brownish colora- 

 tion. In one way they are very different in habit from other 

 birds ; they hold the bill in the water till they finish drinking, 

 instead of raising the head at each mouthful. Most species 

 produce a whistling sound of the wings while in flight.
