 ley as far north as Minnesota, and eastward as far as Cayuga Co., N. Y., and 

 winters in the tropics. Its occurrence here is accidental, and there are but 

 three records of its capture, one of a male taken in Kings County, L. I., (Dutcher, 

 Auk, X, 1893, p. 277), of a male taken at Highland Falls, May 17, 1875 (Mearns, 

 Birds Hudson Highlands, p. 154), and one of a specimen taken at Boonton, 

 Morris Co., N. J., in September, 1887 (Judd, Auk, XIV, 1897, p. 326). 



*Chestnut-sided Warbler {Dendroica pciisylvaiiica) . With us it is a com-

 dent. It arrives early in Alay, and the return migration occurs between August 

 10 and October i.

 numbers. It passes northward about the middle of May and returns in Sep- 

 tember.

 BlackpoU is one of our most abundant migrants 

 and is the last of the transient Warblers to pass

 journey in September.
