PREFACE. 



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

 birds which 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 Ameri- 

 can/ Ornithologists' Union, and the number in the margin opposite the 

 specific name corresponds with the number on the label of each specimen 

 of that species, in the Biological Section of the Provincial Museum. 



Species marked (*) are wanting to complete the collection.
