The Canadian Field-Naturalist 



147 



The observations on which the following list is 

 based were begun in 1907; but at first records were 

 kept only in a sketchy fashion. As the knowledge 

 of the observers grows, they find greater interest 

 in referring to their records, which are being made 

 with increasing attention to detail. In compiling 

 the list, no species has been included unless 

 identified as positively as is possible by sight alone; 

 and care has been taken especially to remove all 

 doubtful records of species not usually seen in the 

 vicinity. 



1. Larus argentatus. Herring Gull. — Flocks 

 of fifteen or less frequently seen flying overhead

 together on Lake Ontario in spring.
