Further, the area is home to the only thick-billed murre
bird colony in the western Canadian Arctic, and is a feeding ground for the nearby Cape Parry Migratory Bird Sanctuary.

Conservation biology of the Thick-billed Murre
in the Northwest Atlantic.
The dominating species in Greenland bird hunting are the thick-billed murre
and the common eider.
Long-term effective population sizes of thick-billed murre
colonies appear to be on the order of 104 pairs (see Appendix), whereas breeding ledges within colonies probably contain on the order of 10s of murres (see above).
The area is also home to the only thick-billed murre
bird colony in the western Canadian Arctic, as well as a feeding ground for the nearby Cape Parry Migratory Bird Sanctuary.
A Review of Thick-Billed Murre
Banding in the Canadian Arctic, 1950-2010.
For example, a female Thick-billed Murre
that forages efficiently (perhaps an older, more experienced bird) might produce a large egg and also feed her chick so well that it grows more rapidly.
Other data were collected at Thick-billed Murre
colonies in the Northwest Territories, Canada, at Prince Leopold Island (74 [degrees] 48[minutes] N, 79 [degrees] 25[minutes] W) in 1975-1977 (Gaston and Nettleship 1981), Coburg (75 [degrees] 48[minutes] N, 79 [degrees] 25[minutes] W) and Bylot (73 [degrees] 46[minutes] N, 80 [degrees] 23[minutes] W) islands in 1979 (Birkhead and Nettleship 1981, 1982), Digges (62 [degrees] 33[minutes] N, 77 [degrees] 50[minutes] W), Hantzsch (61 [degrees] 55[minutes] N, 65 [degrees] 00[minutes] W), and Akpatok (60 [degrees] 10[minutes] N, 68 [degrees] 15[minutes] W) islands in 1980-1982 (Gaston et al.

, Uria lomvia, in the Arctic.

We describe the demographic consequences for a colonial nesting seabird, the Thick-billed Murre
(Uria lomvia), of exceptionally intense mosquito parasitism and predation by polar bears in a particular year.
