before their usual time, some of the later ones were even later 

 than normal. This was true, also, of the migrating birds. 



Day after day brought few or no new arrivals, and it seemed 

 as if the spring migration was over. 



Migration goes on. — On the night of the 13th there was a 

 great flight of birds from the South in New York City, and 

 several new arrivals appeared in Massachusetts on the 14th. 

 On the 15th a flood of migration came through Massachusetts 

 and passed into northern New England and New Hampshire. 

 This flight came with a change in the wind, which shifted from 

 easterly to southwesterly with rising temperatures. During 

 these two or three days practically all the species of summer 

 birds arrived, but mostly in small numbers. After this the 

 birds continued to come slowdy until, on the 21st and 22d, 

 with south winds and very high temperatures, there came 

 what seemed to be the greatest flight of the season. Even

 warblers. Shore birds appeared in immense numbers, and a 

 large flight of Loons passed Cape Cod. Among the rare birds 

 reported were a male Blue Grosbeak and a male Black-headed 

 Grosbeak in Middlesex County, Massachusetts. 



Jnne, 1921. 



This was a dry month in southern New England, with the

 able for nestlings, and great numbers of young birds were 

 reared successfully. The period was so dry that it was im- 

 possible for Robins and other birds which feed much on the 

 ground to secure the usual numbers of earthworms and grubs. 

 Therefore there were many complaints of depredations on 

 cherry trees and cultivated strawberries. During the first two 

 weeks of June there was some evidence of continued migration. 

 Cuckoos were not noted in some localities until the first or 

 second week of the month, and in some cases Indigo Buntings 

 were not seen until about the middle of the month. On June 

 9 a band of 200 Surf Scoters and White-winged Scoters still 

 remained off Long Island. Bonaparte's Gulls and shore birds 

 were still there. On the 20th six migrating Nighthawks were
