BIRDS OF INDIANA. 579 



Peninsula of Michigan (Cook, Birds of Michigan, p. 34). Mr. Ridg- 

 way notes that it breeds at Lake Koshkonong, Wis. (Birds of 111., Vol. 

 II, p. 247). From there they breed in suitable localities northward 

 to the Arctic coast. They have not been reported from Alaska (See 

 article by William Brewster, Bull. Nutt. Orn. Club, 1879, p. 13). 



17. (72) Sterna dougalli MONTAG. 



Roseate Tern. 



Adult in Summer. Top of head and nape uniform black; mantle 

 pale pearly-blue; upper tail coverts and tail silvery white; below pure 

 white, tinged with pink; bill black, reddish at base; feet, coral-red. 

 Winter and Immature. Plumages change as in other species. 



Length, 14.00-17.00; wing, 9.25-9.75; tail, 7.25-7.75; depth of fork, 

 3.50-4.50; B., 1.50. 



RANGE. North America, from West Indies and Central America 

 on the Atlantic coast to Massachusetts; casually to Nova Scotia; ac- 

 cidental in the interior. Breeds throughout its United States range. 

 Winters south of the United States. 



Eggs, 3, deposited on ground, similar to those of the last species, 

 1.65 by 1.12. 



Accidental visitor. Rare. Nothing has ben added to the history of 

 this bird in Indiana. I know of no other record of its occurrence in 

 the State than that given by Dr. Haymond, in Proceedings Philadel- 

 phia Academy of Science, 1859, and later in the Indiana Geological 

 Survey, 1869. Dr. Wheaton gave it upon the authority of Mr. Wins- 

 low as occurring on Lake Erie (Birds of Ohio, p. 562); Dr. Langdon 

 notes its occurrence near Cincinnati (Revised List of Cincinnati Birds, 

 p. 21); Prof. Cook and Dr. Gibbs both give it as a bird of Michigan. 

 The former refers to a specimen recorded in the list of the collection 

 of the Kent Scientific Institute. Of course, its occurrence in the in- 

 terior can only be considered accidental. 



SUBGKNUS STERXULA BOIK. 



18. (74.) Sterna antillarum (LESS.). 



Least Tern. 



Adult in Summer. Very small; "bill yellow, usually tipped with 

 black; mantle, pale pearly grayish blue, unchanged on the rump and 

 tail: a white frontal crescent, separating the black from the bill, 

 bounded below by a black loral stripe reaching the bill; shafts of two 

 or more of the outer primaries. Hack on the upper surface, white un- 

 derneath; feet, orange." (Wheaton). Adult in Winter. Similar;
