11. Stercorarius parasiticus Linnaeus, parasitic jaeger. 
Eskimo: Ishungak; Issungak, according to Hantzseh. 
One specimen of this bird was collected. It was secured September 
4 , 1925, at Koukjuak river, west Baffin island. A few others which were 
thought to be this species were seen along the west coast of Nettilling lake 
in late August. Kumlien (1879, p. 95) says that he rarely saw this bird in 
Cumberland sound and that it does not breed there. Low (1906, p. 315) 
records the species as breeding on Southampton island, as being common 
in Roes Welcome, and less common farther north. Hantzseh (1914, p. 157) 
noted the species in many places on Nettilling lake. “Perhaps as frequent 
at Tikerakdjuak as S. longicaudus or somewhat more frequent." He noted 
many on Koukjuak river at the beginning of September. A half-fledged 
juvenile was taken by him on August 14, 1910. 
12. Stercorarius longicaudus Vieillot. long-tailed jaeger. 
Eskimo: Ishungak; Ischungak, according to Hantzseh. 
A pair was collected at Nettilling lake on June 25, 1925. A few more 
were observed at the same time and a number of others a little later in 
the season, about Nettilling lake. Kumlien (1879, p. 95) saw a few of 
these birds in upper Cumberland waters in June, 1878, after which they 
soon disappeared. Low (1906, p. 315) states they are less common than 
5. parasiticus in Roes Welcome; he saw them occasionally in the waters 
to the northward. Two specimens were collected by Burwash at cape 
Dorset in the summer of 1924. The species is recorded by Hantzseh (1914, 
pp. 158-159) as breeding and rare in July in the neighbourhood of Tikerakd- 
juak, south side of Nettilling lake. At this place on August 1, 1910, he 
notes : 
“A large part of the birds observed seem to be rather young creatures, not of an age 
for breeding, as shown by plumage, sex organs, and in the case of females, lack of a bare 
brooding spot on the abdomen — eat insects mostly; hairs of a small lemming also found 
in the stomach. At Tikerakdjuak more common than the larger species end of August; 
some few individuals observed in the southwest of Kennedy [Nettilling] lake. The last 
observed about the tenth of September (on Koukjuak river)." 
13. Pagophila alba (Gunnerus). ivory gull. 
Eskimo: Nowyaharsuk. 
One juvenile was collected at Pangnirtung fiord on October 24, 1925. 
J. C. Ross (1835, p. XXXV) records it as breeding commonly at port 
Bowen in northwestern Baffin island, but as rare west of Prince Regent 
inlet. Kumlien (1879, p. 99) remarks that it was very common in Issor- 
tukdjuak fiord (Kingwah) and vicinity for a few days in 1877, just before 
the fiord froze over. None was seen in the spring. He states that it does 
not breed in Cumberland sound. Low (1906, p. 315) records it as occurring 
in early summer in Hudson strait. This species was not noted by Hantzseh. 
14. Rissa tridactyla (Linnaeus.) kittiwake. 
Eskimo: Nowyavah. 
In 1923, many of these birds were observed during July along the 
Labrador coast and in Davis strait, and in mid-August, in Lancaster and 
Strathcona sounds. A few were seen on September 22 near the entrance 
to Cumberland sound. A few days later others were seen off Frobisher 
bay' and Hudson strait.
