CHAPTER XV. THE TERNS, GULLS, 

 AND SKUAS. 



[An important group, including the majority of our sea- 

 birds, most of which are resident, others being mere 

 stragglers. These birds are web-footed, and rapid on the 

 wing. The terns have been termed not inaptly the 

 swallows of the sea, and their swallow-like flight as they 

 skim the waves recalls the little migrants, as does also 

 their awkwardness on land. They lay their eggs on the 

 earth without any approach to a nest. They are, in some 

 localities, great enemies of the gulls, destroying their 

 eggs and young. Nine residents ; twelve regular, eleven 

 irregular, visitors.]
