If you carefully keep your bird records by county, be sure to use the specific hotspots in Mount Tom State Reservation so that the birds will be assigned to the proper county. The Hampshire-Hamden county line passes through the middle of the park. 

Mount Tom State Reservation covers more than 2,000 acres of land. The park is located in the Connecticut River Valley, just north of Springfield. The park offers 20 miles of hiking trails for all levels of experience, as well as fishing, canoeing, and cross-country skiing on Lake Bray. The park has views of the Pioneer Valley, the Berkshire Mountains, and the Pelham Hills. 

The area is also a great place to bird watch, especially for hawks in the fall.
