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, Savic. — White- 
headed Eagle, “ Bald Eagle.” Not uncommon on the 
sea-shore. I do not think it breeds now, but it déd twenty- 
five or thirty years ago. 
146. Pandion Carolinensis, Boy. — 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.” Rare 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. Faleo 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. Faleo columbarius, Gu. — Pigeon Hawk. Not 
an uncommon resident. J 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, Box. — 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:
