Abstract:

The black spruce (Picea mariana (Mill.) BSP) forests of Quebec are often harvested according to a single-pass system where clearcuts are separated by 20- to 60-m-wide forest strips. Little is known about the suitability of these strips as habitats for breeding birds. We selected five nonriparian strips, five riparian strips, and five forest control sites located in a forested area of central Quebec. During 1997–1998, we monitored the predation of artificial bird nests baited with a common quail (Coturnix coturnix L.) egg and a plasticine egg and the breeding activity of adult songbirds in strips and controls. Artificial nest predation was high in all sites (72%). The most common predators were specialists of mature coniferous forests: gray jays (Perisoreus canadensis L.) and red squirrels (Tamiasciurus hudsonicus Erxleben). In forest-dwelling bird species, the number of breeding pairs was lower in strips than in controls. We conclude that the small number of forest-dwelling breeding birds observed in strips is not related to an increase in predation pressure following harvest of adjacent forests and that forest strips are not suitable breeding habitats for these species.

Les forêts d'épinettes noires (Picea mariana (Mill.) BSP) du Québec sont souvent récoltées selon un système à un seul passage, où les aires de coupe sont séparées par des lisières boisées de 20 à 60 m de largeur. On ignore la qualité de ces habitats pour les oiseaux nicheurs. Nous avons sélectionné cinq séparateurs de coupe, cinq bandes riveraines et cinq massifs témoins dans une forêt du centre du Québec. En 1997–1998, nous y avons mesuré la prédation de nids artificiels d'oiseaux contenant un oeuf de caille des blés (Coturnix coturnix L.) et un oeuf de plasticine ainsi que l'activité reproductrice des oiseaux chanteurs adultes. La prédation des nids artificiels était élevée partout (72 %). Les principaux prédateurs étaient des spécialistes de forêts de conifères matures : des mésangeais du Canada (Perisoreus canadensis L.) et des écureuils roux (Tamiasciurus hudsonicus Erxleben). Le nombre de couples reproducteurs d'oiseaux forestiers était inférieur dans les lisières comparativement aux massifs. Nous concluons que le nombre inférieur d'oiseaux forestiers reproducteurs observé dans les lisières n'est pas dû à une pression de prédation accrue après la coupe et que les lisières boisées laissées après coupe ne constituent pas des habitats de reproduction de qualité pour ces espèces.
