SCANSORES: TROGONIDjE. 145 



by their enormous bill, which is almost as thick and long 

 as their body, and which is light and cellular internally, 

 arcuated near the end, and irregularly indented along its 

 edges. Their tongue is long, and fringed with barbs on 

 both sides. They inhabit the warm regions of South 

 America. Contrary to what might be supposed, they 

 are- graceful in their movements, and in obtaining their 

 food show a use for their long bills. They dip them 

 down into the deep and hanging nests of other birds, 

 and extract the eggs and young for food. They also 

 feed upon fish, insects, and fruit. They throw their food 

 into the air, and catch it as it descends, and thus swal- 

 low it with greater facility. About twenty species are 

 known.
