77. Spizella monticola Ba'ird. (357.) Tree Sparrow. One specimen 
obtained at Sitka by BiscliofF. Not very common on the Yukon, wliere 
Mr. Kennicott obtained the eggs. I got this species at Nulato, and below 
that point, on the river, sparingly. D. 
7S. Melospiza insignis Baird, n. s. (362a.) Kadiak Sparrow. Ob- 
tained at Kadiak by BischofF, where it is not a rare bird. (See Prof. 
Baird's paper.) D. 
70. Melospiza rufina Baird. (366.) Rusty Song Sparrow. Bischoff 
obtained this species abundantly at Sitka. . D. 
80. Melospiza Liiicolnii Baird. (368.) Lincoln's Finch. Found 
rarely at Nulato, and more commonly at Fort Yukon, where the nest and 
eggs were collected by Mr. Lockhart. D. 
81. JPasserella iliaca Sw. (374.) Fox-colored Sparrow. Abund- 
ant at Nulato, where it arrived May 10th to 15th. Breeds; the eggs 
were obtained at Fort Yukon by Mr. Lockhart. In the months of 
August, 1867, and July, 1868, abundant at the mouth of the Yukon and 
at St. Michael's. One was also shot at Unalaklik, but it seems to prefer 
thickets to the more open tundra. D. 
Not abundant; I shot one specimen during the season of 1865-6, in 
an alder thicket near the fort, and Mr. Pease, who knew the species 
well, also reported having seen a single specimen. B. 
82. Passerella Townsendii Nutt. (375.) Oregon Finch. Bischoff 
collected four specimens at Sitka, and several at Kadiak. D. 
83. Scolecophagus ferriigineus Swains. (417.) Rusty Blackbird. 
Arrives at Nulato about May 20th, where it is tolerably abundant and 
very tame. They breed a little later than some of the other birds. I saw 
one nest commenced about the end of May, but left Nulato before the 
eggs were laid. The latter were obtained by Mr. Lockhart at Fort 
Yukon. Bischoff also got a few specimens at Sitka. D. 
84. Corvtis carnivorus Bartram. (423.) American Raven. Abund- 
ant all the year at Nulato, and every where throughout the Territory, but 
appears to prefer the vicinity of man, being much more common near 
the Indian villages and trading posts than in the unpeopled wilderness. 
It builds on the fixce of the sandstone cliffs at Nulato, selecting some 
little cavity, and occupying the same place for years. The nest is very 
large, of sticks, dry grass, and all sorts of refuse; but the eggs are small, 
six or- eight in number, and very much pointed. They lay very early, 
about April 20th, and the young are hatched some time before open 
water.
