of the list, are the important things. These "All day" studies 

 merely furnish the data. 



The two lists whieh arc appended may be considered fairly 

 representative of the north-western parts of the State of Ohio 

 during May 14th and 15th. It may be argued that because 

 the lists were not made on the same day they are not therefore 

 comparable. To that I would reply that the weather was such 

 that the bird population must have been practically the same 

 on the two days. The region about Tiffin is further removed 

 from Lake Erie than Oberlin. and nowhere approaches near 

 enough to it to be inHuenced by it, rmd that fact will explaui 

 the lack of the distinctively water birds, but otiierwise the two 

 regions are alike. The Oberlin region, therefore, supplies the 

 lake shore conditions which complete the northern Ohio condi- 

 tions affecting bird movements. 



At Oberlin, on the 14th of May, the day opened rainy, with 

 nearly continuous showers until nearly mid-dav, wilh clearing 

 skies in the afternoon. At 2 :30 a. m. the temperature stood at 

 f/8, but a northerly breeze, shifting to north-easterly, and in- 

 creasing to brisk, cooled the air to 48 during nearly the entire 

 day. The early part of the day was spent in the woods, fields, 

 and orchards south of Oberlin, the afternoon in work along 

 the lake shore and the woods, fields and swamps bordering the 

 lake. Thirteen out of a possible sixteen hours were spent 

 a-field. 



At Tiffin, on May 15th, the day began partly cloudy, but 

 clearing, with a temperature of 50, ranging to 80 by mid-after- 

 noon,, with almost no wind. The work covered the region 

 about Tiffin, including every sort of topography. The work 

 began at 3 ::30 a. m., and closed at 8 :30 p. m., with about two 

 hours lost during the day at times when there was little prob- 

 ability of loss in records. 



The participants in this work w-ere Rev. W. F. Henninger, 

 Tiffin, and Lynds Jones, Oberlin. It is to be regretted that 

 other regions in the northern parts of the state are not also 

 represented. 



Species recorded at both places — Tiffin and Oberlin.
