TUBE-X(^SED SWIMMERS. 45 



Atlantic, breeding on St. Kidcla and other 

 Scottish islands that lie far out to sea. 

 South on the American side, in winter, as 

 far as the Georges Banks, where it follows 

 the fishing vessels to pick up the oily matter 

 of fish cleanings cast overboard. Rarely ap- 

 pears in sight of the coast. 



20. LESSER FULMAR. 

 Ver3" similar to the Fulmar, but smaller, 

 16, yet would be difficult to distinguish from 

 it at any great distance. Range and habits 

 about the same. 



SHEARWATERS. 



Birds of the open ocean, but which oft- 

 en approach within a few miles of the coast. 

 They are of varying sizes but none are very 

 small. Differ from the Fulmars in having a 

 more slender bill, fig. 32. Graceful, easy-fly- 

 ing species which seldom rise high above the 

 water and often fly in small flocks close to 

 the surface, frequentlj' in lines side by side.
