166. Dendroica pcnnsylvanica. Chestnut-sided Warbler. A tol- 

 erably common spring migrant from May 9 to May 24. It was not 

 noted in the fall. The Marshalltown cemetery was a favorite resort 

 for this species and I saw more there than in all other places com- 

 bined. 



167. Dendroica castanea. Bay-breasted Warbler. A rare spring 

 migrant. It was noted on May 14 and 19, 1913, and May 18 and

 was not recorded in the fall. 



168. Dendroica striata. Black-polled Warbler. A common 

 spring migrant from May 3 to May 25, most abundant from the 

 17th to the 25th. In the fall it was noted only twice, a single bird 

 on August 23, 1913, and two on September 7, 1914. 



169. Dendroica fusca. Blackburnian Warbler. The Blackburn- 

 ian warbler was a tolerably common spring migrant from May 3 

 to May 22. It was not usually found in any numbers, three being 

 the greatest number noted on any one date. A single bird taken 

 on August 10, 1914, and another the following day are the only 

 fall records. 



170. Dendroica virens. Black-throated Green Warbler. A tol- 

 erably common spring migrant from May 4 to May 22. Only in- 

 dividual birds were noted on most dates, but on May 10, 1913, over 

 fifty singing males were counted. In the fall it was recorded on 

 September 19, 1913, and September 7, 1914.

 river. It was not noted in the fall.

 and common summer resident which first appeared May 3 and was 

 last seen September 21. On May 28, 1914, Hartly Vogt found a 

 nest containing two eggs and two cowbird eggs. Singing males 

 were common during June and July, 1915, on Mormons Ridge.
