VU. H. Fleming.) Rare on Great Slave lake. (oss.) Nutting 
records a specimen taken near Grand Rapids, Saskatchewan river 
in the summer of 1891. (Predle.) This species occurs as an occa- 
sional visitant to the coast of Bering sea, from the Yukon mouth 
to St. Michael at least, and is undoubtedly found still more fre-

BREEDING Notes.—This bird is occasionally shot in Toronto 
marsh. It breeds abundantly on small islands in Lake Michigan. 
On June 1oth, 1894, Mr.Van Winkle collected a number of clutches 
for me on Gravel Gul! islands, Lake Michigan. Nests, in hollows 
in the sand, containing mostly three eggs each. Mr. McIlwraith 
in ‘“ Birds of Ontario,” says this species nests singly, but he is 
mistaken, as it breeds in large colonies like other terns. (azne.) 
65. Royal Tern. 
Sterna maxima BovD. 1783. 
Northward to Massachusetts and the Great Lakes. (4.0.U. Lis¢.)
