three miles to the north of Ayers Cliff, also four Yellow Warblers 

 as well as a Meadowlark. As regards the latter species, things have 

 not materialized as I had expected, for, although their very early 

 arrival gave promise of an increased number of breeding pairs, 

 I have failed to notice them, in fact the bird mentioned above is 

 the last record for the year so far as my own observation goes, 

 although Mr. Greer saw one on November 12. The pair that 

 nested in the meadow near my house in 1917 failed to do so this 

 year, although they frequented the same ground from March 22 

 to April 20 and then disappeared, probably to carry out the 

 decree of nature by extending their range in these parts, as they 

 certainly are new birds to the area within recent years. On the 

 twenty-seventh a pair of Warbling Vireos visited our orchard, and 

 I had hopes of their remaining to breed, but they left in the after- 

 noon. Two days later the unmistakable notes of a Whip-poor-will 

 were heard, and on the thirty-first or last day of the month I 

 obtained a male example of a Black-poll Warbler out of an apple 

 tree in our orchard, this elevation being rather over 1,000 feet above 

 sea level. This example made the second only seen in eight years, 

 the previous one being near Ayers Cliff on May 28 of last year as 

 already recorded, the elevation of that locality not being much 

 over half that of the present one. 



The advent of June brought high hopes of an abnormal nesting 

 season for Warblers, and such proved to be the case, for never in 

 my experience have I located so many breeding pairs of Black- 

 throated Blue, Black-throated Green, Blackburnian and Canada 

 Warblers. In addition to finding the nests and eggs of all 

 the above (one nest of the Canada Warbler being a beautifully 

 domed example similar in every respect to a miniature Ovenbird's), 

 I also came across those of the Northern Parula, Magnolia, Chest- 

 nut-sided and Maryland Yellow-throat. 



The greatest red-letter day of all, however, was June 24, when I 

 saw for the first time in summer a pair of Bay-breasted Warblers 

 and later on discovered their nest and set of four eggs. This 

 nest was entirely different from that of any other Warbler I have 

 come across so far, being characterized by its large size and the 

 irregularity of outline given to it by the long coniferous twigs which 

 composed its exterior, some of these twigs measuring 1\ inches.
