Note: — The following table gives the average date of 

 the first arrival of each bird together with the data from 

 which it was reckoned, for the seven years from 1897 to 1903 

 inclusive, as observed in Lincoln Park, Chicago, by the au- 

 thors. The record for 1902, in the absence of the authors, 

 was kept by Mr. Harold V. Bozell. 



Attention is called to the fact that many birds which are 

 common in the neighboring country are rare in the Park. 

 Among these may be mentioned the Red-winged Blackbird, 

 Bobolink, Warbling Vireo, Prairie Horned Lark and Tufted 

 Titmouse.
