Family TROCHILID^. Hummingbirds. 



Hummingbirds are peculiar to America, ranging from Alaska 

 to southern South America. More than 400 species are recognized, 

 most of which are restricted to tropical parts of South and Central 

 America. Some 18 species occur in North America, but only one is 

 found in eastern United States. When flying the rapid movements 

 of the wings produce a distinct humming sound. The food consists 

 largely of insects, but they also eat the juices of flowers.
