During the summer of 1926, the species was seen only at rare intervals 
along the south coast from Amadjuak bay to cape Dorset and Bowdoin 
harbour. On August 7 a family of two adults and seven juveniles was 
observed at Amadjuak bay. Ptarmigan were said to be fairly common 
at Amadjuak bay in 1925. 
J. C. Ross (1826, p. 99) records the species from port Bowen in October, 
1824, where it was also seen from March to May, 1825. Kumlien (1879, 
p. 83) collected a single specimen in Cumberland sound, 1877-78. Hantzsch 
(1914, pp. 143-146) remarks that this species was apparently much rarer 
during the winter of 1909-1910 in Cumberland sound than the willow 
ptarmigan. The rock ptarmigan was repeatedly noted on his journey 
to Nettilling lake in May and June, 1910. At Nettilling lake in July it is 
recorded as one of the most common of the large birds. The first young 
were seen on July 31. Large flocks were noted on Koukjuak river in early 
September, but the birds were scarcer later in the month. Hantzsch notes 
the occurrence of the species in the vicinity of Foxe basin on October 20, 
and specimens were taken by the Eskimo accompanying him. Hesse 
(1915, pp. 182-191), reporting on the Hantzsch collection, discusses the 
possibility of the Baffin Island birds belonging to the subspecies Lcigopus 
rupestris reinhardti (Brehm), but is inclined to follow the opinion of Hantzsch 
that the birds from west of Davis strait belong to the subspecies L. r. 
rupestris (Gmelin). 
Specimens of both birds and eggs were collected by the Donald B. 
MacMillan expedition to southwest Baffin island, 1921-1922. 
66. Astur atricapillus (Wilson), goshawk. 
A single specimen was taken by Kumlien (1879, p. 82) at Niantilic, 
Cumberland sound, September 19, 1877. This species was not noted by 
Hantzsch nor the present writer. 
67. Archibuteo Iagopus sanctl-johannis (Gmelin). rough-legged hawk. 
At cape Dorset on June 3, 1926, a mated pair of this species was 
observed and the female collected. The birds were frequenting a cliff 
near the sea, and gave the impression that a nest was nearly completed, 
a supposition that was confirmed by finding a fully developed egg in the 
oviduct of the specimen taken. On June 9 a solitary bird was observed. 
An Eskimo furnished a specimen which he had shot near cape Dorset on 
July 26. Two hawks, referred to this species, were seen at Amadjuak bay 
on July 30 and August 5, respectively. 
Low (1906, p. 318) records the species in the spring at Fullerton, which 
is not far distant from Baffin island. One specimen and eggs were collected 
by the MacMillan expedition to southwest Baffin island, 1921-22. 
Hantzsch makes no reference to this species. 1 
68. Haliaeetus albicilla (Linnaeus), gray sea eagle. 
On two different occasions a very large bird, which appears referable 
to this species, was observed by the police at Pangnirtung. Kumlien 
(1879, p. 82) noted the bird on two occasions at American harbour in 
October, 1877, and records a breeding pair at Kingwah fiord, 1878. It 
was not noted by Hantzsch nor the present writer. 
1 No hawks nor owls were observed during the 1928 Arctic Expedition. Their rareness was attributed to the 
scarcity of lemmings and hares.- It.M.A.
