Résumé Le parc marin Saguenay–Saint-Laurent (PMSSL) est situé dans l’une des zones les plus productives de l’estuaire du Saint-Laurent et supporte des nombres importants d’oiseaux aquatiques à l’année longue. Malgré ce fait, aucune étude détaillée n’a encore été faite sur l’utilisation des habitats côtiers de cette région par l’avifaune en hiver. Pour combler cette lacune, des inventaires aériens et terrestres ont été effectués pour mieux quantifier la répartition, l’abondance et le comportement des oiseaux aquatiques hivernant dans le PMSSL. Les résultats confirment l’importance du PMSSL pour les oiseaux aquatiques hivernant dans l’estuaire du Saint-Laurent et indiquent aussi que les oiseaux se déplacent à l’intérieur du PMSSL en fonction des marées, de l’état des glaces et des vents. Les espèces de canards les plus abondantes incluent le Harelde kakawi (Clangula hyemalis), le Harle huppé (Mergus serrator), le Garrot à oeil d’or (Bucephala clangula), le Garrot d’Islande (B. islandica) et le Canard noir (Anas rubripes). Quatre espèces de goélands s’y retrouvent en abondance, soit le Goéland arctique (Larus glaucoides), bourgmestre (L. hyperboreus), argenté (L. argentatus) et marin (L. marinus). On note aussi la présence de Guillemots à miroir (Cepphus grylle) en milieu pélagique, de Bécasseaux violets (Calidris maritima) sur les îles et îlots du large et de quelques Petits Garrots (Bucephala albeola). Les données des recensements d’oiseaux de Noël suggèrent une augmentation des effectifs de Canards noirs, Canards colverts (Anas plathyrynchos), Garrots d’Islande et Harles huppés. Par contre, on a observé un nombre inférieur de Hareldes kakawis ces dernières années.

Nesting Season

We studied intraspecific nest parasitism in an island nesting population of Red-breasted Mergansers (Mergus serrator) in New Brunswick. Of the nests examined, 64% contained eggs from more than one female. This estimate is probably low because the criteria to detect parasitism were conservative. Parasitized nests were initiated, on average, 3 days earlier than normal nests. Parasitic laying occurred throughout the nesting season. A larger proportion of eggs hatched from normal (89%) than from parasitized (75%) nests because 14% of the eggs in parasitized nests were laid during the host's incubation period and failed to hatch in time. A greater percentage of eggs hatched from parasitized nests during the peak nesting period. Parasitized and normal nests produced the same number of ducklings. There was no difference in the percentage of dead, infertile, and lost eggs from normal compared to parasitized nests. The number of nests containing at least one dead egg increased with clutch size. Most host females accepted parasitic eggs during incubation without deserting. Incubation was prolonged on parasitized nests and on nests with low synchronization of embryo development. Nest parasitism is a common reproductive tactic in at least some female Red-breasted Mergansers.
