t!Cal)Ie of d^ccurrence. 



In this table the birds observed by the authors in Lincoln 

 Park, Chicago, are arranged according to the order of their 

 comparative frequency. The abundance of the birds, that 

 *is, the number of individual birds of different species, is in 

 no wise shown but simply the relative representation of each 

 species. For instance, out of a total of 454 mornings cover- 

 ing observations during six years, the Robin was seen on 383 

 different mornings. The record for 1902, during the absence 

 of the authors, was made by Mr. H. V. Bozell.
