45. Otus vulgaris -wilsonianus, {Less.) Allen. — Long-eared 

 Owl. — A single individual seen at Brown's Valley. 



46. Circus cyaneus hudsonicus, {Linn). Schl. Marsh Hawk. — 

 Common all over the prairie. 



47. Buteo borealis, (Gm.)Vleill. Red-tailed Hawk, — Seen at both 

 places. 



48. Buteo borealis krideri, /7oo/ie.s\ 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 Valley, 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 imder 

 tail coverts. There are a few dark spots between the tibise and upon 

 the flanks, but not nearly approaching the quantity on the young of B. 

 borealis or caluriis. This bird has become very tame, and is a great pet, 

 allowing itself to be handled, and distinguishes persons. 



49. Buteo swainsoni, Bp. Swaixsox's Hawk. — A nest and three 

 eggs of this Hawk were taken at Brown's Valley 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 91 inches, depth 2| ; external diameter 19 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-wixged Hawk. — 

 A single individual seen at Herman. 



51. Cathartes aura, (Zi«7i.) ///. Turkey-Buzzard. — Several seen 

 at Herman and Elbow Lake. 



52. Ectopistes migratoria, (Linn.) Sw. Wild Pigeox. — A single 

 specimen seen at Brown's Valley. 



53. Zenaedura carolinensis, (Linn.) Bp. Carolixa Dove. — Com- 

 mon. 



54. Pedioecetes phasianellus columbianus, (Orel) Cs. Sharp- 

 tailed Grouse. — The common Grouse of this region.
