This dataset is associated with the article authored by Jacques Régnière, Lisa Venier and Dan Welsh entitled "Avian predation in a declining outbreak population of the spruce budworm, Choristoneura fumiferana (Lepidoptera: Tortricidae)" which will be published in the "Insects" scientific journal.
The impact of avian predation on a declining population of the spruce budworm, Choristoneura fumifereana (Clem.), was measured using single-tree exclosure cages in a mature stand of balsam fir, Abies balsamea (L.), and white spruce, Picea glauca (Moench.) Voss. Bird population censuses and observations of foraging and nest-feeding activity were also made to determine the response of budworm-linked species to decreasing food availability.
