Ellesmere Land, Prince Regent Inlet (Port Bowen), and presumably 
Hudson Bay. It was stated by the late Manly Hardy to have nested 
on an island in Penobscot Bay 50 years ago (about 1847) and a 
bird, and egg were taken. Stone refers 17 specimens from Point 
Barrow, Alaska, to this form. In Europe breeds from Jan Mayen, 
Iceland, Spitzbergen, Franz Josef Land, and Nova Zembla to the 
Siberian coast (eastern limits not determined) and Bennett Islands, 
76° 39’ N, 
Winter range.—From Southern Greenland and Hudson Bay south 
to Maine. Irregular, but at times common, from Massachusetts, 
southward, New York (Long Island), New Jersey, and Delaware to 
South Carclina (Anderson). Occasionally common on the Great 
Lakes, straggling to northern Ohio (many taken 1896), Indiana 
(December, 1896), and central Iowa (two specimens). In Europe 
winters farther north, rarely south of Norway, Great Britain, and 
the North Sea. 
Spring migration.—Said to arrive at Franz Josef Land as early 
as March 9; at Prince Regent Inlet, west of Baffin Land, early in 
June. Northern Greenland, Cape York, May 10; Saunders Island, 
May 20; Cape Sabine, June 11. 
Fall migration—Birds leave their nesting grounds by early Sep- 
tember. The last seen in northeastern Greenland, latitude 74°, 
August 1. Migration in the eastern United States usually occurs in 
December and through the Great Lake region during November or 
early December; Ontario, Ottawa, November 25 to December 8. 
Egg dates—Bird Rock, Gulf of St. Lawrence: 16 records, June 
5 to July 25; 8 records, June 18 to 26. Greenland: 8 records June 10 
to July 18; 4 records July 3 to 12. Eastern Labrador: 4 records, 
June 10, July 1, 2, and 11. 
URIA LOMVIA ARRA (Pallas). 
PALLAS’S MURRE, 
HABITS. 
The western form of Uria lomvia known as Pallas’s murre (Uria 
lomvia arra) is decidedly larger than the eastern or Atlantic form; 
the bill is larger and more slender and the white of the maxillary 
tomium is duller or more grayish. The “crowbill,” as it is called 
by the sailors, is the most important, probably the most numerous, 
and certainly the most generally distributed of the birds of Bering 
Sea. To the natives it is most valuable as an egg bird, for its eggs 
are large, palatable, abundant, and easily obtained; its flesh is also 
desirable as food. While cruising about the Aleutian and Pribilof 
Islands, in the extensive fogs which prevail there almost constantly
