WARBLER NOTES FROM WAYNE COUNTY, 

 MICHIGAN. 



BY J. CLAIRE wool). 



Mr. P. A. Taverner's interesting paper in the Wilson Bulle- 

 tin for December, 1908, on ornithological observation in this 

 locality impresses one with the difference a few miles can 

 make, especially in warbler migration. Normal years he re- 

 gards May 4 as marking about the height of the warbler mi- 

 gration while a reference to my note-book establishes Alay 15 

 as the average date in the zone of my observations. During 

 the season of 1908 he found practically no warblers until May 

 17, when they rushed through in almost a day. This doubt- 

 less refers to a section north of the city, for southwest of the 

 city and other portions of the county I found the warblers in 

 normal abundance. The spring season opened with several 

 flocks of Myrtles and a Pine on April 19 and thence transients 

 were noted on most all days afield, concluding with a Black- 

 burnian and three Black-polls on May 28. 



I regard the above as about the normal range and, for con- 

 trast, wish to state that the very remarkable season of 1907 

 opened with five Myrtles on April 7, and concluded with three 

 Mourning on June 30. The autumn of 1908 was so divided 

 between the warblers, waders and hawks that I can not fix the 

 status of local warbler abundance by a comparison with the 

 three previous seasons which were almost entirely devoted to 

 the warblers. However, they seemed a trifle scarce, but I doubt 

 if they departed unusually early. The total time given them in 

 October did not exceed four hours, so the following is proba- 

 bly very incomplete. October 4 — Last of Water-Thrush, 

 Blackburnian and Cape May. October 6 — Last of Tennessee. 

 October 11 — Last of Yellow-throat, Black-poll and Magnolia.
