67. Cabot Tern. 
Sterna sandvicensts acuflavida (CABoT) RipGw. 1884. 
Accidental along the Great Lakes. 
In the spring of 1882 Dr. Garnier noticed three individuals of 
this species coursing around a mill-pond not far from his residence 
at Lucknow, Ont. He shot one and the writer saw it after it was 
mounted. (Mcllwraith.) 
69. Forster Tern. 
Sterna forstert NUTT. 1834. 
Only a casual visitor on Lake Ontario in spring and fall. (d/Ze- 
Ilwraith.) ~ Possibly a regular migrant at Toronto, Ont. I have 
examined only two specimens. (/. 7. Fleming.) Summer resident 
about the large lakes of Manitoba; nesting among the reeds. 
(Z. T. Seton.) Rare on Many island lake, Sask. (Bzshop.) This 
species may be said to be regularly found wherever the common 
tern is numerous in Manitoba but west of that province the only 
locality at which I authenticated its presence by collecting in 1906 
was at Manito lake, Sask. (Geo. Atkinson.) In the summer of 
1881 the writer found them abundant on lakes Manitoba, Water- 
hen and Winnipegosis where they were breeding in numbers in 
the bordering marshes. West of Manitoba their place is chiefly 
taken by the common tern, as only one pair was seen by Spread- 
borough at Indian Head in a residence of three months in 1892. 
Richardson says they extend northerly to lat. 57°. 
BREEDING Notes.—On June 18th, 1894, I found an immense 
colony of these birds breeding on an island in Shoal lake, Man- 
itoba. The nest was made ina hollow in the sand, and contained 
three eggs, resting on a few straws. (D¢ppie.) It is not common 
at St. Clair flats, Ont., but nests have been taken there by Mr. J. 
A. Morden, but only a few nests of this species to many of the 
next. (W. Saunders.) 
70. Common Tern. 
Sterna hirundo Lixn. 1758. 
This is truly the ‘* common tern,” as it breeds abundantly from 
the coasts of Labrador southward to the Grand Manan, N.B., on
