This remarkable bird, the ' Skimmer,' has the upper bill ranch .shorter than the 

 lower. The bill is tine and compressed at the point and flexible. It associates in 

 flocks, and flies close to the water, skimming over its surface, and occasionally dipping 

 in its lower bill. What it feeds on is unknown, as Jerdon never found anything in 

 the stomach but a little oily fluid.

The Boatswain birds are oceanic in their habits, but perch and build on trees. 

 Jerdon regards them as related to Gannets and Terns.
