10, 1S89. In 1S90 and 1S91 they bred abundantly in a gravel pit near 

 Early's farm, departing in the first week of August. 



Stelgidopteryx serripennis. — I found one of this species dead in July, 

 1S90, but never saw a living example although I searched diligently. 



Ampelis cedrorum. — Common summer resident. 



Vireo olivaceus. — Abundant summer resident in maple woods and 

 bushes. Departs Sept. 2-6. 



Vireo philadelphicus. — I shot a female of this species Aug. 6, 1889, in a 

 raspberry patch, the fruit of which it was eating. I secured an immature 

 specimen Aug. 7, 1890, and observed two adults Sept. 6, 1890, one of 

 which I secured. 



Vireo gilvus. — Not a common summer resident. Departs Aug. 6-10. 



Vireo flavifrons. — One specimen Aug. 5, 1891. 



Vireo solitarius. — One taken by T. G. White in August, 1891. I have 

 not the exact date at hand. 



Mniotilta varia. — Not a common summer resident but an abundant 

 migrant. Found during summer in the evergreens on the steep bluffs. 

 First migrants arrive Aug. 7-10; common by Aug. 26; last seen Sept. 2-6. 



Helminthophila pinus. — On Sunday, July 1, 18S9, I saw a nne male of 

 this species in an evergreen tree. He permitted the closest scrutiny, 

 sometimes approaching within a few feet of my head in his search for 

 food. I could not find him again the next day. 



Helminthophila chrysoptera.- — Not present in 18S9 and 1S90. In 1S91 

 a number were constantly observed in the bushes until July 26. 



Helminthophila ruficapilla. — Rare summer resident and common 

 migrant. In summer found among the evergreens; during migrations, 

 among the bushes. The first migrants straggle along about Aug. 10; the 

 bulk arrives in a body about Aug. 25-Sept. 5, and all disappear within a 

 day or two. 



Helminthophila peregrina. — Common migrant. Found in bushes and 

 evergreens, rarely in the open woods. Arrives Aug. 6-24; bulk arrives 

 inside of a week; and all leave in a few days, Aug. 28-Sept. 6. 



Compsothlypis americana. — Abundant migrant in low bushes ami 

 maple woods. First seen Aug. 22-Sept. 1 ; the bulk arrives almost imme- 

 diately ; and all depart soon, Sept. 5-6. 



Dendroica tigrina. — Not uncommon migrant in 1890 and 1891. First 

 seen Aug. 30; departs Sept. 6. 



Dendroica aestiva.- — -Abundant summer resident. Breeds in the ever- 

 greens. At first very common; every day sees a diminution of their 

 numbers, until by Aug. 10-12 the last have departed. 



Dendroica cserulescens. — In 1SS9 this species was observed only as a 

 common migrant, but in the succeeding years I found it a not uncommon 

 summer resident. In summer it inhabits the maple woods, but in migra- 

 tion it frecjuents the evergreens. First seen, in 18S9, August 15. Becomes 

 common Aug. 9-21, and departs about the middle of September. 



Dendroica coronata.— In 1SS9 one female was shot July 13, after which 

 the species was not observed until the migration. In 1S90 and 1891 they
