often are seen soaring high over the river, more like a Bnteo 

 than a Falco, and uttering their loud, squealing- cries. After 

 the young leave the nest, gravity brings them down to the val- 

 ley bottom, but they are soon able to fly sufficiently well to 

 keep out of gunshot. The whole family usually disappears 

 soon after the young are strong on the wing, and I have not ob- 

 served them about their ledge after Aug. 15th. Mr. G. H. 

 Thayer writes me that he usually finds one or two every summer 

 on the higher ridges of Mt. Monadnock, but does not know of 

 their breeding. On the coast, Mr. W. E. Cram notes the bird 

 at Hampton Falls as a migrant in the months of March and 

 April, September and October. 



113. Falco columbarius Linn. Pigeon Hawk. 



A rather rare spring and fall migrant. Dr. A. P. Chad- 

 bourne ('87, p. 103) records that one was " seen " in the Great 

 Gulf, Mt. Washington, at about 3,000 feet, on July 8, 1886. 

 The bird was not secured, however, so that the record does not 

 certainly establish the bird's presence in New Hampshire dur- 

 ing the breeding season. I have never found it in the fall mi- 

 grations among the White Mountains, when other hawks are 

 common, and all the many specimens seen or shot have been of 

 other species. Mr. C. F. Goodhue has taken the bird at Web- 

 ster, however. Amateur local lists of birds usually include this 

 species as a summer resident, where doubtless the Sharp- 

 shinned Hawk is the bird in question. 



114. Falco sparverius Linn. American Sparrow 

 Hawk. 



An uncommon spring and fall migrant and a rather rare sum- 

 mer resident of the Transition areas of the state, breeding spar- 

 ingly in the valley bottoms well up towards the bases of the 

 White Mountains. At Intervale, I have known of but a single 

 pair to nest in the vicinity during ten years' observation ; this 

 pair bred for one or two seasons in a large dead tree on the Saco 

 valley meadows, about eight years since. A few appear also in 

 late summer in the migration down the valley. I have seen
