It is perhaps not unimportant to state that the Spring of 
1920 was very backward and that the foliage on May 22nd 
seemed to be fully ten days to two weeks later than normal. 
This general condition caused a rather irregular period of 
migration, and generally speaking, a numerical scarcity of all 
species. 
A rather belated attempt was made to organize observing 
parties to cover other sections of Essex County, but aside from 
the Haverhill region, which was covered by B. S. Griffin, no 
other lists were turned in. Two species were checked by Mr. 
Griffin and not recorded on the Ipswich River Trip, the Indigo 
Bunting and the Warbling Vireo. It is hoped that during the 
next and succeeding years an increasingly larger part of the 
County will be covered.
