THE AUK. 



A Quarterly Journal of Ornithology. 

 Official Organ of the American Ornithologists' Union. 



As the official organ of the Union, "The Auk" is 

 the leading ornithological publication of this country. 

 Each number contains about 100 pages of text, a 

 handsomely colored plate, and other illustrations. 

 The principal articles are by recognized authorities, 

 and are of both a popular and scientific nature. The 

 department of "General Notes" gives brief records 

 of new and interesting facts concerning birds con- 

 tributed by observers throughout the United States 

 and Canada. Recent ornithological literature is re- 

 viewed at length and news items are commented on 

 by the editors. "The Auk" is thus indispensable to 

 those who would be kept informed of the advance 

 made in the study of birds, either in the museum or 

 in the field. 



Price of current volume, $3.00. Single numbers, 

 75 cts.
