PREFACE. 



In the following Check List I have endeavored to include all the 

 birds that have been positively known to occur in the Province of 

 Ontario. 



In cases where I have no personal knowledge of the record, I have 

 given the authority for it. 



The nomenclature adopted is that of the Check List of the 

 American Ornithologists Union.
