Third Census of Seabird Populations of the Gaspé Peninsula, Québec, 2002

Abstract: In the tradition of the quinquennial census of seabirds in the Migratory Bird Sanctuaries along Québec’s North Shore, which began in 1925, this paper presents the results of the first three seabird censuses of the Gaspé Peninsula conducted in 1979, 1989, and 2002, with an emphasis on the third census and on changes in seabird populations that occurred between the second and third censuses. In 1979 the population of seabirds was estimated at 134,163 birds, and this increased 72% to 231,186 birds in 1989. The up… Show more

“…13) have been similar throughout the region, with most populations increasing before 1990 and decreasing subsequently, although the very large colony of murres at Funk Island (not included in Fig. 13) has remained stable (see below; Chardine et al 2003;Robertson et al 2004;Rail and Coter 2007;Coter and Rail 2007;JFR and GJR unpublished data) and Great Island, Witless Bay (southeastern Newfoundland) also approximately doubled between the 1970s and early 2000s (Robertson et al 2004).…”

“…We do not know where the Boot Island Herring Gulls spend their time outside the breeding season, although some birds may winter along the eastern seaboard of the United States (see Drury and Nisbet 1973*;Gaston et al 2008*). It may, however, not be coincidental that the rapid decline in Herring Gull numbers on the north shore of the Gulf of St. Lawrence from 1988 to 1993 (Chapdelaine and Rail 1997;Cotter and Rail 2007) …”

“…Les guillemots marmettes s'accommodent souvent des sites de nidification du petit pingouin, qu'ils ont d'ailleurs tendance à coloniser, allant parfois même jusqu'à monopoliser l'espace et exclure ce dernier avec le temps (Bédard, 1969). Il ne faudrait pas se surprendre de voir l'espèce continuer son expansion dans les prochaines années, d'autant plus que les effectifs se portent bien dans le golfe du Saint-Laurent (Cotter et Rail, 2007;Rail, 2009;Rail et Cotter, 2015).…”

“…Par contre, il n'aurait colonisé que beaucoup plus récemment la plupart des autres îles qu'il occupe actuellement dans l'estuaire du Saint-Laurent (ECCC, 2017). Alors que l'espèce est nettement en croissance partout dans le golfe du Saint-Laurent (Cotter et Rail, 2007;Rail, 2009;Rail et Cotter, 2015), la tendance observée dans l'aire d'étude depuis 2001 suggère plutôt que le potentiel soit limité ou peut-être réduit sur les îles, surtout avec l'arrivée du renard roux sur certaines (Le Petit Pèlerin et Le Long Pèlerin depuis 2003). L'espèce est aussi à sa limite de répartition vers l'amont du Saint-Laurent, avec seulement deux colonies plus à l'ouest (aux îles Le Pilier de Pierre et Le Pilier de Bois, face à Saint-Jean-Port-Joli).…”
