Sub-Family RHYNCHOPINAE. 



Ch.— The mandibles are of very unequal length, the upper being much shorter and grooved to receive the edge of the lower . 

 from the base their sides are suddenly compressed to the end ; wings very long and narrow ; tail forked and of moderate 

 length; tarsi a little longer than the middle toe ; anterior united by an indented web. 



These birds abound most in the tropics ; they frequent the large hays and the inlets connecting 

 them with the ocean ; their principal food is fish, which they obtain by skimming close to the 

 surface of the water, into which they dip the lower mandible, suddenly closing it into the upper 

 when it comes in contact with their desired prey. They have a peculiar undulating mode of 

 flying. They are said rarely, if ever, to swim or rest upon the water, although possessing 

 webbed feet.
