XXVI. STERNA Linnaus. 1758. 
64, Caspian Tern. 
Sterna tschegrava LEPECH. 1770. 
A tolerably common summer migrant and breeds on many of 
the islands off the coast of Newfoundland. (Reeks.) Very rare 
in Nova Scotia. One specimen shot at Cole Harbour. (Dowzs.) 
One specimen procured at Moose Factory, Hudson Bay. Pack- 
ard.) Not uncommon in the spring and autumn around Hamil- 
ton Bay, Ont. (M/cllwraith.) Rare on Great Slave Lake. (Koss.) 
This species occurs as an occasional visitant to the coast of 
Behring Sea, from the Yukon mouth to St. Michael at least, and 
is undoubtedly found still more frequently south to the known 
haunts of the species along the Pacific coast of Asia. (JVelson.) 
BREEDING Notes.—This bird is occasionally shot in Toronto 
marsh. It breeds abundantly on small islands in Lake Michigan. 
On June toth, 1894, Mr. Van Winkle collected a number of 
clutches for me on Gravel Gull Islands, Lake Michigan. Nests 
singly in hollows in the sand, containing mostly three eggs each. 
Mr. MclIlwraith in “Birds of Ontario,” says this species nests 
singly, but he is mistaken, as it breeds in large colonies like 
other Terns. (Razne.)
