the eggs, and in the remainder only enough material had been

64. Caspian Tern. 



Sterna caspia Pall. 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. {Dozvns.) One 

 specimen procured at Moose Factory, Hudson bay. {Packard.) 

 Not uncommon in the spring and autumn around Hamilton bayi 

 Ont. {Mcllwraith.) Regular spring migrant at Toronto, Ont. 

 Sometimes occurs in flocks of up to 50. I have no fall records. 

 (/. H. Fleming.) Rare on Great Slave lake. {Ross.) Nutting 

 records a specimen taken near Grand Rapids, Saskatchewan river 

 in the summer of 1891. {Preble.) 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- 

 quently south to the known haunts of the species along the Pacific 

 coast of Asia. (Nelson.) 



Breeding Notes. — This bird is occasionally shot in Toronto 

 marsh. It breeds abundantly on small islands in Lake Michigan. 

 On June loth, 1894, Mr.Van Winkle collected a number of clutches 

 for me on Gravel Gull islands. Lake Michigan. Nests, in hollows 

 in the sand, containing mostly three eggs each. Mr. Mcllwraith 

 in " Birds of Ontario," says this species nests singly, but he is 

 mistaken, as it breeds in large colonies like other terns. {Rai?ie.) 



65. Royal Tern. 



Ster?ia maxima Bodd. 1783. 

 Northward to Massachusetts and the Great Lakes. {A.O.U. List.)
