fish, after which it darts into the water with great force, seizes them, 
and instantly returns ; for though it is web-footed, it is never seen to 
swim or dive. It is commonly known by the name of sea swallow, 
from its actions on wing being similar to that bird. On the south coast 
of Devonshire it is called gull-teazer, as it is frequently seen to pursue 
and persecute the lesser gulls till they disgorge, which it dexterously 
catches before it reaches the water. Whether this property is common 
to the other species we have not been able to ascertain ; but in general 
their manners and habits are very similar ; none of which have ever 
been observed to settle on the water. This is sometimes, on its first 
arrival, found skimming over fresh-water rivers and lakes for a few 
days ; but we do not find that they breed in such places in England. 
It is found in most of the northern parts of Europe during the breed- 
ing season, even as far as Greenland and Spitzbergen, as well as North 
America, where in New England it is called mackarel gull ; and at 
Hudson’s Bay is known by the name of black-head. Mr. Pennant 
calls it the greater tern. The young birds are mottled with brown and 
white.
