Worcester County Migrant Birds. 
For the convenience of those students interested chiefly in the 
smaller, more easily observed, birds, we have divided this list into two 
sections : Land Birds, including those from Cuckoos to Bluebirds ; 
and Water and Game birds (from Grebes to Owls). 
The following list was prepared with the co-operation of the mem- 
bers of the Brewster Club, and of the classes of the Natural History 
Society under the leadership of Mr. Wendell P. Parker and Miss 
Helen A. Ball. 
It is divided into three classes : 
Migrants. Those birds that breed in or pass through the county 
but do not commonly spend the winter here. 
Winter Visitors. Those birds not commonly breeding in the 
county but occurring here during the winter months. 
Residents. Birds found in the county throughout the year.
