There were thus 58 species wbicb were more tban five days either 

 too early or too late in their arrivals, or almost 33% of the species 

 involved. No account is liere taken of the Water Birds, because 

 there is nuich less certainty that accurate records were made of 

 their movements. It is worth noting that most of the species which 

 arrived ahead of their schedule belonged to the earlier parts of tb.e 

 migration, and that about half of those which arrived behind sclied- 

 nle belonged to the late waves. 



The largest warbler and thrush migration usually occurs about 

 the middle of May, but tliis year the lieaviest movement was on 

 the 121st and 2-U{\ of May. with many of them remaining until the 

 first of June, due to chilly and rainy or cloudy weather. 



Vegetation was as far advanced in the middle of April as it usu- 

 ally is in tlie middle of May, but apparently there was not a cor- 

 respondingly early develoi)ment of insect life, although there wer? 

 considerable numbers of insects associated with the foliage. While 

 this unseasonable advance of vegetation was clearly not a purely 

 local phenomenon, since much the same sequence of weather had 

 prevailed southward into the Gulf states, it could liardly be ex- 

 I)ected that the 1)irds which normally reach the southern border of 

 ihe United States about the middle of April would have felt the 

 pull of the unseasonable conditions in the Lake Kegion, and hence 

 would not keep up with the vegetation and development of insect 

 life. This would account for the marked paucity of birds during 

 the warmth of the first two weeks of April when conditions seemed 

 to be unusually favorable for birds of the warbler type. 



We have to sorrowful,ly record the absence of Chickadee and Car- 

 olina Wren. The woods seem comparatively cheerless without them. 

 No reason can be assigned for the disappearance of the Chickadee, 

 and none that is satisfactory for that of the Carolina. Wren. On 

 the other hand, there have come to the region during the migra- 

 tions (ladwall. (iolden I'lover. Bewick's Wren, and Mockingbird. 

 Of course the Gadwall is found in the immediate vicinity of hike 

 Erie, but it was never before recorded for the Oberlin Water Works 

 reservoir. There were two Mockingbirds, one of them in full song. 

 and they are still with us. A ten-day war on the English Sparr()^^■ 

 has resulted in the presence of more native birds in the village.
