rose above the surrounding trees. On this dead tree-top the 

 large size of the bird was well seen. A Red-tailed Hawk flew 

 about the Eagle while perching here, making darting flights at 

 it. Presently it took wing again and disappeared from our view 

 behind the trees which stood in the foreground. But about 

 three hours later it was again in the sky, pursued by a Red- 

 tailed Hawk, and flew off in the direction of Mt. Starr King. 

 In its several flights the complete whiteness of the tail was many 

 times observed. On July 4, while the town celebration of Inde- 

 pendence Day was proceeding on Jeflerson Hill in the afternoon, 

 my assistant, who had seen the Eagle with me at Cherry Pond, 

 informed me that one passed in flight over the assembly from 

 Mt. Starr King toward the pond, attracting much attention. On 

 August 22 an adult bird was again seen in Lancaster near the 

 Connecticut River, flying southward. On September 27 an 

 adult bird was once more seen over the Jefferson valley, as we 

 were driving on the turnpike. Not improbably these four 

 records are based upon but two birds. But, however that may 

 be, the season of 19 10 was the first to furnish a succession of 

 records. 



In Dr. Allen's " Birds of New Hampshire " Mr. Vyron D. 

 Eowe, of Randolph, testifies "that a pair of Bald Eagles has 

 summered for perhaps twenty five years on the Presidential 

 Range and that until seven years ago [1895 ?], or thereabouts, 

 the nest was nearly at timber line on Mt. Adams, but that some 

 one robbed it, and the birds have left the site, though he still 

 sees them on the range at intervals during the summer ; in 1902, 

 Mr. Lowe first saw the birds on March 23d." 



56. Falco peregrinus anatum. Duck Hawk. 



Mr. Nathan Clifford Brown writes me : ' ' During the first week 

 of August, 1907, I saw one morning at Jefferson some magnificent 

 evolutions on the part of a Duck Hawk. He swooped several 

 times with astonishing velocit)^ toward a farmhouse and recov- 

 ered himself with wonderful quickness just before reaching the
