In addition to this area of New England providing great fly fishing opportunities, there are other outdoor opportunities including birding.  There are several areas along the Connecticut River that are traps for migrating birds in the spring and fall and one Internationally recognized Audubon Society Important Bird Area at which 221 species have been recorded.  See the link below for details.  Cold River Guide Service also provides guided bird outings.  The rate is $25 per person or a flat rate of $150 for a group up to 15 people for up to four hours of birding.
