This bird differs from the preceding chiefly in having a bright red bill tipped with black, and the under parts washed with pearl. These are the most common Terns on the New England coast, nesting abundantly from Virginia to Newfoundland. These beautiful Terns, together with others of the family, were formerly killed by thousands for millinery purposes, but the practice is now being rapidly stopped. In May and June they lay their three, or sometimes four eggs on the ground as do the other Terns. They are similar to the preceding species but average shorter. Data.--Duck Is., Maine, June 30, 1896. Three eggs in marsh grass about fifty feet from beach. No nest. Collector, C. A. Reed. [Illustration 055: Brownish buff.] [Illustration: Forsters Tern.

ARCTIC TERN. _Sterna paradisaea._ Range.--Northern Hemisphere, breeding from New England northward to the Arctic Regions and wintering south to California and the South Atlantic States. A similar bird to the last, differing in having the bill wholly red and the feet being smaller and weak for the size of the bird. A more northern bird than the last, breeding abundantly in Alaska, both on the coast and in the interior. In the southern limits of its breeding range, it nests in company with the Common Tern, its nests and eggs being indistinguishable from the latter. When their nesting grounds are approached, all the birds arise like a great white cloud, uttering their harsh, discordant "tearrr, tearrr," while now and then an individual, bolder than the rest, will swoop close by with an angry "crack." On the whole they are timid birds, keeping well out of reach. The nesting season is early in June. Eggs like the preceding. Data.--Little Duck Is., Me., June 29, 1896. Three eggs in a slight hollow on the beach, three feet above high water mark. 72. ROSEATE TERN. _Sterna dougalli._ Range.--Temperate North America on the east coast, breeding from New England to the Gulf. These are the most beautiful birds, having a delicate pink blush on the under parts during the breeding season; the tail is very long and deeply forked, the outer feathers being over five inches longer than the middle ones; the bill is red with a black tip. They nest in large colonies on the islands from Southern New England southward, placing the nests in the short grass, generally without any lining. They lay two or three eggs which are indistinguishable from the two preceding species. 73. ALEUTIAN TERN. _Sterna aleutica._ Range.--Found in summer in Alaska and the Aleutian Islands.
