are seldom seen after the middle or latter part of August, but 

 in 1906 two were observed on October 2 in South Lancaster. In 

 1 9 10 two single birds only were seen throughout the season, and 

 these were at widely separated points in Randolph. 



136. Vireosylva olivacea. Red-eyed Vireo. 



An abundant summer resident in all the woodlands of the 

 lower slopes of the mountains, up to about 3000 feet, and of 

 the valleys ; also of the shade trees of the villages. The song 

 extends with little abatement to late August and is much given 

 in the remaining days of August and in the early days of Sep- 

 tember. The last are usually seen between September 20 and 

 25. In several seasons, 1901, 1906, 1907, 1908, and 1910, a bird 

 or two birds have been seen in the early days of October, the 

 fifth day, in 1908, being the latest. Ten to twelve singing males 

 have been found occupying the fifty-acre piece of woodland on 

 the Highland. On some all-day drives sixty to sixty-five sing- 

 ing birds have been recorded. 



137. Vireosylva philadelphica. PhiladeIvPhia Vireo. 



A rather rare fall migrant, usually seen in the valley near 

 the river or in the vicinity of Cherry Pond, but sometimes on 

 the Highland and beside mountain roads at considerable eleva- 

 tion above the valley. In 1903 one was seen on September 13 

 in the valley at the foot of the Highland. In 1904 one was 

 again seen there on September 14, and a week later two birds 

 were observed passing through the growth on the bank of the 

 river in company with a Red-eyed Vireo and a Blue-headed 

 Vireo with other birds. In 1907 nine individuals were noted in 

 succession between September 11 and 19. Six of these were 

 seen at various points in the valley, while one was observed on 

 the Highland and two up the South Branch road at some alti- 

 tude above the valley. In 1908 two were seen on September 11 

 up this same South Branch road and two weeks later one in the 

 small growth about Cherry Pond. In 1909 seven or eight differ-
