year at Fullerton, Hudson bay but only in small numbers during 
the winter, the main body migrating southward early in October. 
Thousands were seen at that date crossing Chesterfield inlet in flocks 
of several hundreds. They return from the south in May usually 
in small flocks. (A. P. Low.) North of the Mackenzie to the 
Arctic coast, rather rare. (Ross.) This species is not nearly so 
plentiful as the willow ptarmigan, and we only met with it in any 
considerable numbers from Horton river, Barren Grounds, to the 
shore of Franklin bay. Very few nests were found to the eastward 
of that river or on the coast or ‘“‘Barrens’’ of the lower Anderson. 
(Macfarlane.) Common on the summits of most mountains on the 
British Columbia mainland and on Vancouver island. Quite com- 
mon at Atlin, B.C. (Kermode.) Three males were taken at White 
Pass summit, B.C. (Bishop.) This beautiful bird is a common 
resident of the Alaskan mainland, from Bering strait to the British 
border on the east, including the entire north and south extent of 
the mainland. (Nelson.) This species is found on all the hills 
and higher ground along the entire coast region of Alaska. In the 
interior it is found only on the mountain chains. It is abundant 
within the Arctic circle down to Kadiak island. It is the only 
species of ptarmigan found on the eastern Aleutian islands. (Turner.) 
This species is a much less plentiful resident at Point Barrow than 
the willow ptarmigan. It breeds not far from the station, but I 
never found its nest. (Murdoch.) 
BREEDING NoTes.—The rock ptarmigan builds its nest of grass, 
etc., lined with finer grasses and some of its own feathers. The 
usual complement is eight to ten eggs. (A. P. Low.) I have two 
clutches of eggs from Herschell island, one of eleven the other of 
eight eggs. Both nests consisted of hollows in the moss lined with 
a few feathers. (W. Raine.) 
302a. Reinhardt Ptarmigan. 
Lagopus rupestris reinhardt (BREHM) BLAstIus. 1862. 
The only species of the genus that inhabits Greenland, where it 
occurs equally on the east as on the west coast, found on both Sabine 
and Clavering islands; in great abundance on Parry islands and 
Melville peninsula. (Arct. Man.) A resident at Ivigtut, but most 
abundant in winter. (Hagerup.) According to Sabine, this bird
