says it has been taken at "Lexington, near Boston, and 

 at Upton, in 1849." No record of its very recent cap- 

 ture, however, in this section. I have never met with it. 



145. Haliaetus leucocephalus, Savig. — White- 

 headed Eagle, " Bald Eagle." Not uncommon on the 

 sea-shore. I do not think it breeds now, but it did twenty- 

 five or thirty years ago. 



146. Pandion Carolinensis, Bon. — Fish-Hawk. Not 

 a common summer resident, growing less so every year. 

 Perhaps a few breed in the interior, but it is doubtful. 



147. Falco anatum, Bon. — American Penguin Fal- 

 con, " Duck Hawk," " Great-footed Hawk." Bare visitor. 

 I do not think it breeds ; no instance on record of its 

 doing so in this section. This species seems to prefer the 

 more mountainous regions, especially during the breeding- 

 season. 



148. Falco sacer, Forster. — Jerfalcon, "White 

 Hawk." Very rare during winter, perhaps accidental. I 

 have seen this species but once, — November 4, 1868, — 

 flying high above the snow-topped mountains of New 

 Hampshire, steering northward over the unbroken forests, 

 — even thus early in the season covered with snow, and 

 almost a solitude, — deserted by nearly all of the feathered 

 tribe. 



149. Falco COlumbarius, Gm. — Pigeon Hawk. Not 

 an uncommon resident. I think it breeds, as I have a 

 specimen taken during the breeding-season, with all the 

 evidences of its incubating. Perhaps more uncommon dur- 

 ing winter. 



150. Falco sparverius, Linn. — Sparrow Hawk. Not 

 a very common resident. Breeds. 



151. Astur atricapillus, Bon. — Goshawk, "Part- 

 ridge Hawk," "Blue Hawk." Not uncommon in winter. 

 Some few undoubtedly breed. A pair remained in Wes- 

 ton, near a heavily wooded district, during the breeding-
