in 1901) ; young birds have been observed leaving the nest May 

 24, and fresh eggs have been seen as late as June 24 (1902), when 

 15 nests were found on an area not exceeding one acre in Green's 

 marsh. 



These birds are, of course, more or less musical at all times dur- 

 ing their stay, but it is in the fall that they are most noticeable as 

 musicians. Then they gather up in great flocks and on bright 

 sunny days hold their "campmeetings." The first of these in 1900 

 was held on August 7 and thereafter for two months or more they 

 were quite frequent. These meetings are in the nature of con- 

 certs or choruses and are remarkable in many ways. The birds 

 select a prominent tree, usually isolated from others, in the top 

 of which they congregate and remain for hours pouring forth their 

 soul in song. Sometimes they move to another tree or group of 

 trees and continue the chorus.

ICTERUS SPURIUS (Linmeus)

102. BALTIMORE ORIOLE 



ICTERUS GALBULA (Linnaeus) 



Summer resident, arriving late in April and remaining until 

 in September. One of the most cheery birds of summer, frequent- 

 ing the maples and other trees about the cottages. Its brilliant 

 colors and musical note attract attention throughout the summer 

 and its beautiful pendent nests may be seen in the late fall and 

 winter when the leaves have fallen from the trees. 



We have definite records as follows : July and August, 1899 ; 

 July 17 to August 27, 1900; April 29, 1901, first heard, first seen 

 next day, and almost daily from then on until late in the sum- 

 mer. A fine long nest was seen at the north edge of Green's marsh, 

 and the young were frequently heard inside. Another nest near
