35. Begulns satrapa Liclit. (162.) Golden - crested Wren. 
BischofF obtained a large number of this species at Kadiak, and also at 
Sitka, where it appears to replace in great measure the last sjiecies. It 
has not been obtained in the Yukon Territory. D. 
36. Hydrobata mexicana Baird. (164.) Water Ouzel. Feet ashy. 
Eyes black. This bird is essentially solitary. Several specimens were 
obtained in January, February, and MarcJi, always near some open, 
unfrozen spot, in some small stream, such as the Nulato River. It is 
never seen except in the most retired spots, and almost invariably 
alone. I have never heard it sing. I always examined the crop, but 
never found anything in it. The Indians told me, and my own observa- 
tion confirmed it, that this bird, when disturbed, will dive into the water 
even in mid-winter; and as it is never found but near open water, I sus- 
pect it obtains its food from thence. I noticed the legs and bill of some 
of the specimens were light yellow-ochre color, and others dark slate 
color. Obtained near Sitka by Bischoff. D. 
37. Budytes flaim Lin. (165a.) Sliip "Nightingale," Behring 
Sea, St. Matthew's Island bearing W. 90 miles; wind NW. by W. ; 
August 10th, 3 P.M. — A small bird flew aboard, apparently from St. 
Matthew's, that being the nearest land. It was in a much exhausted con- 
dition, and died the next morning, having been placed in a cage. After- 
ward obtained at St. Michael's, Norton Sound, by Pease and Bannister. 
Eyes black. The specimen was a male. D. 
I first observed this species at St. Michael's about the 9th or 10th of 
June, and from that until well into the month of August, they were 
among the most abundant birds, perhaps, after Plectr. lapponicus, the 
most abundant of the strictly terrestrial species. During the month of 
June, I observed them generally in flocks of twenty to thirty individuals. 
It appeared to me to be a rather shy bird; most of the few specimens 
obtained were shot on the wing while flying overhead. 
In its flight it is like our common goldfinch, Chrys. tristis, rising with 
a few strokes of its wings, then closing them, and describing a sort of 
paraboloid curve in the air. The only note which I heard and identified 
as uttered by this species was a khid of faint chirp, hardly to be called a 
Bong. 
This bird, like the two species of Plectrophanes and Passerculus 
anthinus, appeal's to prefer the open country, and was rarely observed 
in the low brush, the only approach to timber found on the island. B. 
38. Anthus ludovicianus Licht. (165.) Titlark. Universal. 
From British Columbia to Behring's Straits, common every where 
on open country, near the sea or river side. Obtained by Elliott in 
British Columbia; Sitka, Bischoff"; Ounga Ishmd ; Pen. Aliaska ; Amak 
Island ; St. Michael's, Norton Sound ; Yukon River, from Fort Yukon 
to the sea ; Behring's Straits. D.
