Common permanent resident. 



352. Haliaetus leucoceplialus (Z ?>/«.) Bald Eagle. 



Permanent resident, but becoming scarce south of Lake Winnipesauke. 



The bald eagle is occasionally seen in the vicinity of lakes and streams ihrough- 

 out our area, especially along the Merrimack river. It is known to breed as far 

 south as Franklin. «- While it is highly probable that it nests farther south in the 

 more secluded and mountainous districts of Hillsborough county authentic reports 

 to that effect are lacking. Kirds which have been reported by inexperienced ob- 

 servers as " large hawks " have sometimes on investigation turned out to be eagles. 

 In fact, the eagle, while not common in our area, is not so rare as is popularly 

 imagined and there is much to learn in regard to its distribution and annual 

 movements.
