No. 5.— Notes on Birds from East Siberia and Arctic Alaska. 
By W. SprRaGcuE Brooks. 
INTRODUCTION. 
In the spring of 1913, several graduates of Harvard University 
organized a hunting expedition in northern waters. Through the 
generous codperation of Col. John E. Thayer and Prof. Theodore 
Lyman, Mr. Joseph Dixon and the writer had the pleasure of accom- 
panying the expedition as zodlogical collectors. Our itinerary was 
as follows. : 
Leaving Seattle on the power schooner Potar Bear, Capt. L. L. 
Lane in command, we proceeded up the “inside” passage of south- 
eastern Alaska, stopping for a few hours at Woewodsky and Kupreanof 
Islands on April 9 and 10, and at two points on Icy Straits April 11 
and 12. Thence to the Semidi Islands on April 18 and 19, and from 
there to several points along the Alaskan peninsula where little time 
for work was at our disposal. 
Obtaining a few supplies at Unalaska we proceeded to Copper 
Island arriving on May 6. Here the snow was too deep for travelling 
and in two days we left for Bering Island where winter conditions also 
caused much trouble. 
May 10 found us at Petropavlovsk and from this date to May 27 
we worked on the Kamchatkan coast from Petropavlovsk to Cape 
Africa. At the latter point ice conditions prevented further travel 
in a northerly direction and we crossed Bering Sea to St. Lawrence 
Island. This Island and the Chukchi Peninsula of Siberia were the 
centre of our activities during June, including a brief stop at Big 
Diomede Island in Bering Strait. 
In July our work on the Siberian shore was extended to Cape 
Serdze from which point we crossed to Cape Lisburne, Alaska, and 
Point Barrow arriving at the latter Point on July 24. The favorable 
ice conditions east of Point Barrow soon ceased and we encountered 
every possible unfavorable condition of ice and weather during August, 
finally being forced to go into winter quarters at Humphrey Point, 
Alaska, after nearly losing the vessel. Humphrey Point lies about 
thirty-five miles west of the Alaskan-Canadian boundary. Though
