Throughout the summer months, the observer will choose his 
territory with reference to the species that he wishes to find. 
General directions on this subject may be found in almost any of 
the manuals mentioned in the bibliography. Of course the more 
varied the character of the country, the greater the variety of 
species likely to be found there. Woodland that borders on a 
stream or pond and is also near fields and meadows, will usually 
have a large and varied bird population. Some of the best terri- 
tory in Andover is found along the Shawsheen River.
