Nulato, January 10th, 1867. — An Indian brought in a bullfinch alive, 
but badly wounded, which he had shot from a small tree near the 
fort. He had never seen anything like it before, nor had the Russians. 
On showing it to Captain Everett Smith, some time afterward, he said 
he had seen several flocks of the same species near XJlukuk. This speci- 
men was a male, with black eyes, bill, and feet. It was the only bird of 
the kind that I saw during two years. (See Prof. Baii'd's paper.) D. 
60. Plnicola canadensis Cabot. (304.) Pine Grosbeak. In- 
dian name, Kiyoutah. Collected at Sitka and Kadiak by Bischoflf. 
Extremely common near Nulato, and, in fact, where ever there are trees 
throughout the Yukon Territory. Frequents groves of willow and 
poplar near open places, and especially the water side, in winter. In 
summer they go into more retired thickets to breed. 
I have opened the crops of a great many, and always found them filled 
with what I for a long time supposed to be spruce buds; but, on closer 
examination, I found that they were the hearts of the poi^lar buds, with 
the scales and other external coverings carefully rejected. I have never 
found anything else in their crops. They have no song, only a twitter 
and long chirp. The flesh is good eating. D. 
Gl. Curvirostra americana Wilson. (318.) Red Cross-bill. Ob- 
tained at Sitka by Bischoflf. Not observed in the Yukon Territory. 
D. 
62. Curvirostra leucoptera Wilson. (319.) Not uncommon in 
winter near Nulato; several specimens were obtained February 8, April 
8th and 9th, 1867. They are not found there during the summer. They 
are very expert at opening the spruce cones with their crooked bill, and 
extracting the seeds. D. 
68. Aegiothus linaria Cab. (320.) Red Poll. Common at St. 
Michael's winter and summer. B. 
Very common at Nulato in winter, and very little less so in summer. 
The nest is usually lined with hair, and externally covered with moss, 
dry grass, etc., in bushes near the ground. They begin to build about 
May 15th. The eggs are laid about June 1st, and the young are flying 
about toward the end of July. 
The young of the first year are dark, often with a small patch of brown 
on the breast, besides the usual streaked markings. The red forehead is 
scarcely, and sometimes not at all, perceptible. AVith their spring moult, 
the red forehead becomes pronounced; the breast of the male becomes 
nearly white, with a trace of pink on the throat. The same part in the
