FAMILY LV. GANNKl'S (StiLIDJE) 



A small family (8 species) of large, heavy, sea-birds, which, 

 except when migrating, are never found far from land. In 

 their movements through the air they alternate their flapping 

 with short periods of sailing. They are large-bodied birds, 

 but have such exten- 

 sive air cavities under 

 the skin as to render 

 them very light on 

 the water ; thus they 

 swim with great ease. 

 Associated in small 

 flocks, these birds fly 

 with outstretched 

 neck, usually at some 

 height above the 

 waves, and, when a 

 fish is seen, close the 

 wings and shoot down- 

 ward like an arrow 

 to secure the prey.
