Sequence variation in the guillemot (Alcidae: Cepphus
) mitochondrial control region and its nuclear homolog.
The adaptive significance of the reproductive pattern in the black guillemot Cepphus
Black Guillemot Several thousand pairs breed in crevices on (Cepphus
cliffs along the south and west coasts and grylle) adjacent to the North Spit (Gaston et al., 2012).
Black Guillemot: Black guillemots (Cepphus
grille) bred at all three sites.
Lawrence Island contained remains of a black guillemot (Cepphus
grylle; Fay et al., 1990), and one account states that a walrus stomach was "full" of murres (age of birds not given, Nelson, 1969:354).
Observations at these colonies focused on six species, namely thick-billed murres (Uria lomvia), black guillemots (Cepphus
grylle), northern fulmars (Fulmarus glacialis), black-legged kittiwakes (Rissa tridactyla), glaucous gulls (Larus hyperboreus), and common eiders (Somateria mollissima borealis), but we had occasional observations on other species during breeding (Tables 2, 3).
290, he mentions "lummes"; this term, sometimes also rendered as "looms," was the name whalers used variously for the black guillemot (Cepphus
grylle) or the thick-billed murre (Uria lomvia).
If the location was correctly reported, however, the site comprises one larger island and three islets, apparently without breeding arctic terns, but with breeding common eider (Somateria mollissima), black guillemot (Cepphus
grylle) and glaucous gull (Larus hyperboreus).
Britten Harter, University of Manitoba, is studying the effects of global warming and the retreat of Arctic pack ice on the daily chick growth and breeding success of the black guillemot (Cepphus
grylle); and Lea Randall, University of Calgary, is researching the response of insectivorous mammals to insect infestation in the northern boreal forest.
We observed small numbers of other seabirds in deep waters, including Sabine's gulls (Xema sabini), black-legged kittiwakes (Rissa tridactyla), Arctic terns (Sterna paradisaea), black guillemots (Cepphus
grylle), and unidentified auklets (Aethia spp.).
Birds described as dovekies (Alle alle) by Greely must have been black guillemots (Cepphus
grylle), since the reported amount of meat from an individual exceeded 1 pound (0.4 kg).
In contrast, the southeastern Beaufort Sea has only two small seabird colonies: a colony of about 800 thick-billed murres (Uria lomvia) on the cliffs of Cape Parry (Johnson and Ward, 1985) and a colony of approximately 100 black guillemots (Cepphus
grylle) nesting within rock piles and old buildings at Herschel Island (Ward and Mossop, 1986).
