38. Clangula clangnla americana 
(Bonap. ). American Golden-eye 
Duck. It is a common winter 
visitant to the Charles river 
basin, and occasionally to Jamaica 
poud, where Mr. H. B. Bigelow 
saw four birds on November 20, 
1899. 
39. Oharionetta albeola (Linn.). 
Buffle-head Duck. Mr. L. F. 
Foster killed a pair on November 
17, 1879, near the Brookline bor- 
der. 
40. Erismatura jamaicensis (Gmel. ). 
Ruddy Duck. One female was 
shot by Mr. L. F. Foster on 
October 23, 1882, near the town 
border. I have had several times 
ducks occuring on Jamaica pond 
described to me, and there seems 
little doubt their being of this 
species. 
41. Circus hudsonius (Linn.). Marsh 
Hawk. An uncommon migrant, 
and possibly still a rare summer 
resident in upper Brookline. April 
26 to October 31. 
42. Accipiter velox (Wils. ). Sharp- 
shinned Hawk. An uncommon 
summer and winter resident, and 
common migrant. 
43. Accipiter cooperii (Bonap.). 
Cooper's Hawk. A rather uncom- 
mon summer resident, rare in 
winter, but sometimes common on 
migrations. 
44. Buteo lineatus (Gmel.). Red- 
shouldered Hawk. A common 
permanent resident. A careful 
article, with map, on our Brook- 
line Red-shouldered Hawks by Mr. 
F. H. Kennard will be found in 
The Auk (Vol. XL, pp. 197, 271). 
45. Buteo platypterus ( Yieill. ). Broad- 
winged Hawk. On the authority 
of Messrs. F. H. Kennard and N. 
A. Francis I include this species 
as a migrant. 
46. Archi buteo lagopus sancti-johan- 
nis (Gmel.). American Rough- 
legged Hawk. Mr. N. A. Francis 
writes they are not rare as spring 
migrants. The only definite re- 
cord, however, is of a single bird 
seen by Dr. A. L. Reagh on 
January 16, 1897, a few hundred 
yards over the town border in 
West Roxbury. The bird with 
but little doubt entered Brookline.
