MNIOTILTID^E THE AMERICAN WARBLERS. 151 



The first specimen which the writer ever saw was creeping about 

 the eaves and cornices of a frame dwelling house in the center of 

 the town of Mt. Carmel. Very often, however, it could not be dis- 

 tinguished from other warblers, so far as its actions were concerned. 



Mr. Nelson (page 35 of his list) makes the following record of his 

 experience with this species at Mt. Carmel: 



"First noted August 30, when they were found to be abundant in 

 a group of elm trees on the river bank near town. During the 

 succeeding three days they were plentiful, and thirty-six specimens 

 were taken and many more seen. After September 2 not a speci- 

 men was to be found, though diligent search was made. While 

 here they showed great preference for the elm trees before men- 

 tioned, none being found elsewhere. They uttered the faint "cheep" 

 common to most warblers, and one was heard delivering a low 

 song from the top of a tall elm. The notes were so low that even 

 when standing under the same tree the song could only be distin- 

 guished by careful listening." 



The distribution of this species is not yet well made out ; it prob- 

 ably occurs, however, in all parts of the State where there are 

 suitable localities; i. e., densely timbered creek or river bottoms, 

 where large sycamore trees are abundant. Dr. E. M. W. Gibbs 

 informs me (in letter) that he took a specimen at Kalamazoo, 

 Mich-gan, (lat. 40 -25) on May 5, 1877, and another in the fall; 

 and, though probably erroneously, that it probably goes farther 

 north to breed. 



Mr. Nelson records it as being in Cook county a very rare 

 summer visitant from the south. Prof. D. S. Jordan, of Indianap- 

 olis, Indiana, writes that this species is a common summer resi- 

 dent in that vicinity, and that he has trustworthy information of 

 its rather common occurrence, in summer, in the vicinity of Detroit, 

 Michigan.
