148 AUKS, MURRES, AND PUFFINS 
31. Uria lomvia lomvia (Linn.). Briinnicn’s Murre. Ads. in 
summer.— Upperparts, wings and tail sooty black; foreneck somewhat 
browner; tips of secondaries, breast and belly white; base of upper mandible 
greenish, rounded outward beyond edge of lower mandible. L., 16°50 
W., 8°40; Tar., 1°30; B., 1:25; depth of B. at nostril '47. 
Remarks.—Adults are to be distinguished from adults of U. t. troile by the 
darker color of the head, which in lomvia is darker than the throat, by the 
size of the bill and thickening of its cutting edge at the base. Winter and 
immature birds can be distinguished from those of U. t. troile only by the size 
of the bill, which, as the measurements show, is longer in that species. 
Range. ’—Coasts and islands of the n. Atlantic. Breeds from s. Ellesmere 
Land and n. Greenland to n. Hudson Bay and Gulf of St. Lawrence; resident 
in Greenland and Hudson Bay; s. casually in winter on Atlantic coast from 
Maine to S. C., and in interior to n. Ohio, cen. Ind., and cen. Iowa. 
Washington, A. V., several, Dec. 1896. Long Island, W. V. Nov. 22- 
Mch. 24. Ossining, A. V. Cambridge, two records, Nov., Dec. N. Ohio, 
casual on Lake Erie in winter. 
Nests in communities, side by side on the bare ledges of rocky cliffs. Egg, 
1, not distinguishable from that of U. t. troile. Date, Bird Rock, Que., June 17. 
Briinnich’s Murre often nests in the same colonies with the Common 
Murre, which it resembles in habits, and from which, at close range, 
it may be distinguished by its shorter, heavier bill and swollen, whitish 
margin of the base of the mandible. , The downy young of the two species 
can ‘be distinguished by the somewhat hairy, gray-streaked back of 
troile as compared with the more downy, brown mottled back of lomvia. 
Both utter the characteristic screech of young Murres while young 
Razor-bills whistle. This species sometimes invades the interior in 
numbers.

82. Alea torda Linn. Razor-BILLep AuK. Ads. in summer.—Upper- 
parts, wings and tail sooty black; foreneck somewhat browner; tips of 
.econdaries, a line from eye to bill, breast, and belly white; bill black, 
crossed by a white band. Ads. in winter.—Similar, but with sides and front 
of neck white. Im.—Similar to ad. in winter, but with bill smaller and with- 
out white bar. L., 16°50; W., 7°90; Tar., 1°35; B., 1°25. 
Range.—Coasts and islands of the n. Atlantic. Breeds on American 
side of s. Greenland to N. F. and N. B.; winters from N. B. and Ont. to L. I. 
and casually to N. C. 
Long Island, W. V., Nov. 2-Feb. 6. 
Nest, in the crevices and fissures of cliffs and rocky places Eggs, 1-2, 
pale bluish white or buffy, thickly spotted and speckled with chocolate 
markings most numerous and sometimes confluent at the larger end, 3°00 x 
1:90. Date, Bird Rock, Que., May 24. 
“When brooding, it crouches cise not across, the egg, its mate 
often standing near; and both sexes incubate, though the male may 
be seen bringing food to the sitting female. . . . The young flutter 
from the rocks to the sea, or are taken by the neck and carried down 
by the parents. They are at first very loath to follow the old bird in 
diving, and remain crying plaintively on the surface of the water. 
The Razor-bill utters a peculiar grunting or groaning, especially when 
sitting. On the water it may be distinguished from the Guillemot, 
[=Murre] at a distance, by its upturned tail.” (Saunders.)
