48. Accipiter velox. Sharp-shinned Hawk. 



A summer resident ; more common as a fall migrant. Birds 

 are infrequently seen in June and July, but are almost daily 

 noted in August and September, Few remain in early October. 

 When the Flickers are migrating in September in scattered 

 companies, sometimes numbering many birds, they have several 

 times been seen to be pursued by one or two or several of these 

 hawks across the pastures of the Highland, apparently in play. 

 On September i8, 1903, four of these hawks were so engaged 

 in the early morning among a company of half a hundred Flickers. 



Dr. Allen in his " Birds of New Hampshire " records that 

 he saw "a single bird on the rocks near the summit of Mt. 

 Washington on ths 28th of August, 1901." 



49. Accipiter cooperi. Cooper's Hawk. 



A summer resident ; more common as a fall migrant. This 

 species is less frequently seen in June and Juh' than the Sharp- 

 shinned Hawk, and is also less common in the fall migration in 

 August and September. On August 21, 1902, a Cooper's Hawk 

 suddenly darted from the hillside to Israel's River, where were 

 four Kingfishers. These with a chorus of rattles flew off down 

 stream. The hawk did not pursue. On August 21, 1906, an 

 identical date four years later, circumstances were reversed, and 

 a Kingfisher was the aggressive bird and drove off two Cooper's 

 Hawks. 



In the summer of 19 10 a pair nested in the fifty-acre piece 

 of woodland on the Highland. On June 10 one of the parent 

 birds was first noted when I was passing through the wood in 

 the early morning recording its tenants by their songs. The 

 bird called noisily, giving a continuous cackle as it flew about, 

 without coming into view. But a few days later, on the 14th 

 and 15th, glimpses of the bird were obtained as in its flight it 

 came several times within the range of vision. It was not until 

 the 22d that the bird was plainly enough seen to be identified 

 as a Cooper's Hawk. On the 25th the nest was found located 

 in a yellow birch about a foot and a half in diameter at the butt
