WILLOW PTARMIGAN
301. Lagopus lagopus. 15 in.
In winter, white with black tail feathers. In summer, usually reddish-brown with black bars. This species has a much stouter bill than the next.
Nest.—Eggs laid on the ground. Rich buffy, so heavily blotched and streaked with black as to nearly conceal it (1.75 × 1.25).
Range.—Breeds in the northern half of Canada, migrating southward to southern Canada.
301a., Allen Ptarmigan (L. l. alleni), found in Newfoundland, is similar, but in winter the shafts of the primaries are always black.
ROCK PTARMIGAN
302. Lagopus rupestris. 14 in.
In winter, like the last species, except that the bill is smaller, and the lores are black.
Range.—From the Gulf of St. Lawrence and northern British Columbia northward. 302a. Reinhardt Ptarmigan, replaces the last variety in northern Labrador. 303. Welch Ptarmigan (L. welchi), found in Newfoundland, is said to be grayer in summer.
