156. Vermivora peregrina (Wilson) . Tennessee Warbler. — Rare 

 transient; May 26-27. For the past six years I have been anxiously 

 looking out for this warbler without success until May 26, 1917, when 

 three examples were observed, out of which I secured two, and presented 

 them to the Victoria Memorial Museum at Ottawa. The following 

 day I saw another, thus making a total of four only for the year, as none 

 were seen in the fall. The last example was by itself, but the other three 

 were in the company of a mixed flock of other warblers, consisting of one 

 Blackburnian, one Bay-breasted, one Chestnut-sided, two Nashvilles and 

 several Myrtles and Magnolias, as well as a few Ruby-crowned Kinglets. 



157. Dendroica tigrina (Gmelin). Cape May Warbler. — Rare 

 transient; May 22-30; August 27 to September 12. My first acquaintance 

 with this striking and usually rare warbler was on August 28, 1916, when 

 an example was obtained as well as another on the thirtieth, both being 

 given to the Victoria Memorial Museum at Ottawa. Two others were 

 seen on the former date as well as one on September 12, making a total of 

 five for that year. In the following spring they were first seen on May 22, 

 and from that date to the thirtieth a total of twelve were observed, three of 

 this number being obtained and again given to the Museum at Ottawa. 

 In the f?ll they were first noticed on August 27, and from that date until 

 the first of September another seven were noted, making a total of nineteen 

 for 1917, or twenty-four for the two years. They were never very difficult 

 to approach and could generally be found frequenting a certain restricted 

 area. On one occasion I obtained a snapshot of five males and one female 

 in a little tamarack tree, this female, if I remember rightly, being one of the 

 only three seen out of the above total of twenty-four birds. It is a curious 

 fact (not fiction) that the last example seen of this warbler in 1916 was on 

 September 12, and it flew out of the very same birch tree, in which a week 

 later I found the Myrtle Warbler imbibing sap (see ' The Auk,' vol. 34, 1917, 

 pp. 484-485) from sapsucker holes. Could it have been engaged likewise 

 I wonder?, for I have since learned that it has been recorded as doing so on 



' New Providence, Bahamas, see ' The Auk,' Vol. 30, 1913, p. 155. 



158. Dendroica striata (J. R. Forster). Black-poll Warbler. — 

 Rare transient; May 28. The only occasion on which I have come across 

 this warbler was at Ayers Cliff, — about six miles from Hatley, on the above 

 date in 1917, when in a small alder bush near the junction of the river 

 Tomifoby with Lake Massawippi, an adult male was seen at close quarters 

 for several minutes, making identification absolutely sure. 



The elevation of this spot is only some 550 feet above sea level, which is 

 a low one for migrating Black-polls in these parts I imagine, judging from 

 Allen's ' Birds of New Hampshire,' 1903, pp. 57-58, 163-165, in which 

 we are told that the Black-polls at all events in the central and northern 

 parts of the state are only found migrating through the White Mountains 

 at an elevation of 2000 to 4000 feet or more, and the same thing occurs, 

 I believe, in the Green Mountains in Vermont. Judging then from my 

 experience, it looks as though none of the vast multitude of Black-polls
