37. Indigo Bunting Passerina cyanea. Local station 

 substantially the same as the Blue-winged Warbler. 

 Breeding season frequently extends well into July. 

 Eleven pairs. 22 



38. Scarlet Tanager r/raw^a ervtJiromeLis. Inhabits wood 

 borders, usually near roads or paths. One pair built 

 in my home orchard in 1901. There appears to have 

 been a gradual and substantial increase up to the end 

 of the century. The maximum number for 1900 and 

 1901 is twenty birds. Taking into consideration the 

 conspicuous plumage of the males, I still believe that 

 they actually exceed the females in number, 20 



39. Purple Martin Prague stibis. Two or three pairs 

 located in a box erected by Mr. Washington Harris, in 

 1889. Seven years later 1 succeeded in attracting a 

 young pair to quarters prepared for them, and have 

 had a small colony, not exceeding three pairs, ever 

 since. Previous to the above instances, the Martin 

 has been a stranger to the tract, though breeding a 

 few miles away. Much commoner in the Southern 

 portion of the county. 10 



40. Barn Swallow Chelidon crythrogaster. Of the four 

 barns formerly sheltering this bird, one has been de- 

 molished, another burned down, and the third closed 

 against it; the fourth is situated in the valley and ac- 

 commodates about ten pairs. 20 



41. Cepar Waxwing Ampeiis cedronim, Four pairs 

 nesting in shade and fruit trees. 8 



42. Red=eyed Vireo l/ireo olivaceus. This tireless singer 

 chiefly inhabits the woods and thickets. A few pairs 

 may always be found nesting in the shade trees about 

 dwellings. The nest is not hard to find after the 

 leaves have fallen and their number justifies my ap- 

 proximation of tifty-tlve pairs. no 



43. Warbling Vireo yjreo gilviis. 1 have noted but 

 eight pairs in any one year hereabout, two pairs in 

 North Berwvn; all found about large maples near 

 dwelliniis. 4
