330 Wood, Autumn Warbler Migration. [july 



Three birds noted and all adults, the Oct. 7 specimen being a male and the 

 remainder females. 



Cape May Warbler (Dendroica tigrina) . — All adult birds except two 

 junior females, one secured Sept. 3 and the other Sept. 30. This is the 

 first time I have met with the species here. They ranked seventh in total 

 number of individuals for the season. 



Black-throated Blue Warbler (Dendroica cairulescens) . — First 

 noted Sept 3 — an adult male and female. From Sept. 5 to Oct. 14, both 

 inclusive, there was a mixture of both sexes and ages. The Oct. 23 bird 

 was a junior female. Fourth in total number of individuals for the season. 



Myrtle Warbler (Dendroica coronata). — Not enough taken to judge 

 proportion of age and sex to dates. Second in total number of individuals 

 for the season. Much less abundant than in 1905 and departed earlier. 

 Mr. Edward Arnold informs me he has seen this species in January near 

 Battle Creek, Michigan. 



Magnolia Warbler (Dendroica maculosa). — The junior birds first 

 appeared Sept. 3 and the adults on the 15. The three Sept. 30 birds were 

 two adults and one junior — sexes not known. Sixth in total number of 

 individuals for the season. 



Bay-breasted Warbler (Dendroica castanea). — All junior birds and 

 an equal number of each sex. 



Black-poll Warbler (Dendroica striata). — The most common species 

 Sept. 3, and third in total number of individuals for the season. Mixed 

 adults and juniors throughout September. All the October birds were 

 adults, mostly males, but the last specimen was a female. There is no 

 authentic record of this species occurring here in spring but I saw what 

 was probably a small flock May 30, 1905. 



Blackbtjrnian Warbler (Dendroica blackburnice) . — Eight birds noted 

 in all, the only adult being the Oct. 9 bird; this was a male. 



Black-throated Green Warbler (Dendroica virens) . — First noted 

 Sept. 9, an adult female; then a mixture of both sexes and ages inclusive 

 of Oct. 9. The two of Oct. 14 were adult females and the Oct. 21 bird 

 was not secured. Fifth in total number of individuals for the season. 



Palm Warbler (Dendroica palmarum). — One specimen, an adult 

 female Oct. 7. 



Water Thrush (Seiurus noveboracensis) . — Birds secured were of both 

 sexes but ages uncertain. 



Connecticut Warbler (Geothlypis Philadelphia). — The two birds 

 noted were adults. Absent in spring but taken spring and autumn of 

 1905. 



Canadian Warbler (Wilsonia canadensis) . — One of the August 26 

 birds was an adult male, the first in autumn for three years.
