Minneapolis Oct. 15, 1876. and stays sometimes in the southern part of 
the state until the second week in May. 
33. Surnia ulula hudsonia, {Gm.) Cones. Hawk Owl. — A medium-sized 
owl of diurnal habits. So far as noticed it is uncommon in the south¬ 
ern part of the state, though it may be more numerous and breed in 
the northern, timbered part. Taken at Minneapolis Oct. 31, 1876, and 
again Dec. 1, 1876. 
34. Astur atricapillus, (IF//*.) ,/cm/. Goshawk.— The hawk generally 
seen in winter. A bold and powerful bird that preys largely upon 
grouse and hares. Seen at Minneapolis Oct. 9, 1876, and young of 
year taken in Lake Co., Aug. 26, 1879. 
35. Bucephala islandica, ( Gm.) Bd. Barrow’s Golden-Eye. —A beau¬ 
tiful black and white duck likely to occur wherever there is suitable 
open water. Several years ago, before the noise and activity became so 
great about the Falls of St. Anthony, a flock of these ducks used to 
spend the winter in the pool below the cataract. There is in the Uni¬ 
versity Museum a female specimen of B. islandica taken at Min¬ 
neapolis Jan. 13, 1*77. Heretofore the Bucephala occurring in winter 
has been regarded as clangula , and while it is highly probable that 
that species does occur during the winter months, the only winter spec¬ 
imens that 1 have examined thus far is referable to islandica. 
36. Harelda glacielda {Linn.) Leach. —Long-tailed Duck —Occurs on 
Lake Superior. I have in my collection two specimens kindly sent to 
me by Mr. Thos. W. Mayhew, of Grand Marais, Cook Co. They were 
taken at that place, one April 12, 1880, and the other about March 1, 
1881. In answer to an inquiry in regard to the occurrence of the 
species, Mr. Mayhew replied: “They are not considered rare herein 
winter. They make their appearance about October nearly every fall, 
and will remain all winter if the Lake is open; where they go when 
the Lake freezes I cannot say. 1 think they generally leave here about 
May. The Indians call them ‘jack owly.’ ” 
37. CEdemia fusca, Samim. Velvet Scoter Coot. —On two occasions I 
have seen ducks, evidently this species, in the river at Fort Snelling, 
once in January and once in April. 
“ HALF-HARDY.” 
All the species (except Lanius borealis ?) here included under this head breed 
in the State, and when the winters are mild occur throughout the 
the year. 
38. Certhia familiaris. Linn —Brown Creeper. —Avery small, inconspic¬ 
uous bird that is quite generally overlooked. Maybe known by its small 
size, dull markings, and habit of creeping up the trunks and limbs ot 
trees. In its search for food it always begins at the base of the tree 
and passes spirally upward, probing every small hole and crevice with 
its Hue, curved bill. Although sometimes found when the weather is 
quite severe, it is never numerous in the winter. (Dec. 10, 1874 ; Jan. 
19, 1877 ; Feb. 23, 1878.)
