the White Mountains, though it is rather common on the mead- 

 ows of the Saco valley during the migration in August and 

 September. At such times, a single bird will remain in the 

 same neighborhood for several days at a time, evidently finding 

 food plenty, and being in no haste to move southward. 

 Dates : March i6 to November 12. 



103. Accipiter velox ( Wils.). Sharp-shinned Hawk 

 A common spring and fall migrant, and a less common sum" 

 mer resident ; in the southern half of the state, a winter resident. 

 Throughout the heavily-wooded parts of New Hampshire, this 

 hawk is of general distribution during the breeding season, oc- 

 curring well up onto the mountains. In the winter, a few are to 

 be foutid in the lov/er part of the state, and Mr. C. F. Goodhue 

 ('77a, p. 113) has recorded them in this season, about Webster. 

 A northerly winter record for this bird "is that of one obtained 

 at Tamworth, on December 27, 1898, by Mr. R. W. Gray and 

 now in the Howe-Shattuck collection. Throughout the White 

 Mountain region this is by far the commonest hawk during the 

 fall migration and especially in the months of August and Sep- 

 tember, when it is to be found, usually singly, from the fertile 

 vallej^ bottoms, through the woods, even to the summits of the 

 mountains, and I have seen a single bird on the rocks near the 

 summit of Mt. Washington, on the 28th of August, 1901. I 

 have not infrequently heard from this bird, a sharp "chip," 

 much like a PhcEbe's " chip," and usually given when alarmed 

 or as it starts to fly from the perch on which it may have just 

 alighted. 



103. Accipiter cooperii (Bonap.'. Cooper's Hawk. 



A not uncommon spring and fall migrant and summer resi- 

 dent. It breeds regularly over the greater part of the state, 

 and throughout the lower Canadian region, up to about 3,000 

 feet on the higher mountains. 



Dates : March 26 to October. 



104. Accii>iter atricapillus (Wils.). American Gos- 

 hawk. 



An irregular, though sometimes common visitant in late fall
