45. Otus vulgaris wilsonianus, (Less.) Allen. — Long-eared 
Owl. — A single individual seen at Brown’s Yalley. 
46. Circus cyaneus hudsonicus, (Linn). Schl. Marsh Hawk. — 
Common all over the prairie. 
47. Buteo borealis, (Gm.) Vieill. Red-tailed Hawk. — Seen at both 
places. 
48. Buteo borealis krideri, Hoopes. Krider’s Buzzard. — On the 
17th of June we took from one of the large cotton-wood trees on the bor- 
der of the Minnesota River, in Brown’s Yalley, a young Hawk, not more 
than a week old, which we brought back to Minneapolis with us. The 
parent bird soared above the nest while the young bird was being taken., 
and her noticeably white appearance attracted our attention at once, 
and we judged her to be of this species. The growth of the young bird 
has gradually confirmed this idea, as it now, at the age of nearly three 
months, shows unmistakable evidences of being this light variety of the 
Red-tailed Hawk. Its general appearance is white, including the back 
and tail. The forehead and broad superciliary lines are of a buffy tinge, 
as is also the whole breast, becoming pure white on the belly and under 
tail coverts. There are a few dark spots between the tibiae and upon 
the flanks, but not nearly approaching the quantity on the young of B. 
borealis or calurus. This bird has become very tame, and is a great pet, 
allowing itself to be handled, and distinguishes persons. 
49. Buteo swainsoni, Bp. Swainson’s Hawk. — A nest and three 
eggs of this Hawk were taken at Brown’s Yalley from one of the large 
cotton-wood trees before alluded to. It was situated in a fork against 
the trunk, about forty feet from the ground, and was built of dry sticks 
and lined with a few green twigs of the cotton-wood. The eggs were very 
far advanced in incubation. Two of them are of a dirty white color, un- 
marked, while the third is covered with very fine spots and dashes of pale 
brown, thickest at the smallest end. The measurements are as follows : 
2.25 X 1.75 (the spotted one) ; 2.22 X 1.68 ; 2.18 X 1.72. The nest meas- 
ured, internal diameter 9-^ inches, depth 2f ; external diameter 1 9 inches. 
A very fine specimen of this bird was shown us by Mr. J. N. Sanford, of 
Elbow Lake, at which place he had recently captured it. 
50. Buteo pennsylvanicus, ( Wils.) Bp. Broad-winged Hawk. — 
A single individual seen at Herman. 
51. Cathartes aura, (Linn.) III. Turkey-Buzzard. — Several seen 
at Herman and Elbow Lake. 
52. Ectopistes migratoria, (Linn.) Sw. Wild Pigeon. — A single 
specimen seen at Brown’s Yalley. 
53. Zensedura carolinensis, (Linn.) Bp. Carolina Dove. — Com- 
mon. 
54. Pedicecetes phasianellus columbianus, (Ord) Cs. Sharp- 
tailed Grouse. — The common Grouse of this region.
