White on Birds of Mackinac Island. [fury 



were rather common during the summer in the high evergreens. The 

 summer residents departed in a body Aug. i, 1890, and under the date of 

 Aug. 7 Dr. Gibbs wrote from Kalamazoo that the first Myrtle Warblers 

 had arrived. No migrants from the north had yet reached Mackinac. 

 Bulk arrives about the middle of August, and all depart the first week in 

 September. 



Dendroica maculosa. — Found abundantly in the bushes where it is the 

 characteristic summerbird. Departs Sept. 6-11. I detected seven distinct 

 son^s of this species, no one of which is even a variation of the other. 



1. Three notes followed by one lower: che-iveech che-zveeck c/ie-6. 



2. Three sharp clear whistles with a strong ;- sound, then a warble of 

 three notes, the middle the highest, the latter clear cut and decisive: pra 

 pra pra r-f-oo- 



3. Two quick sharp notes followed by a warble of three notes, the middle 

 the highest: the warble is soft and slurred: prtU put purreao. 



4. A soft falsetto warble, different in tone from any other bird song: 

 purra-e-zv/itiy-a. 



5. Of the same falsetto tone, uttered rapidly : prut-ut-ut-ut-ut. 



6. A harsh note like, in miniature, the cry of a Jay : d lay kay kay. 



7. A harsh k-c-c-e-dl, the last syllable higher by a shade, quick, and sub- 

 ordinated to the first part. The alarm note is a sharp zeek.

 Found with D- castanea; dates of arrival about the same. 



Dendroica blackburniae. — Observed during 18S9 only as a very common 

 migrant frequenting maple woods, during its stay. First seen, in 18S9.

 observed at wide intervals.
