Résumé

Capsule Nests of Levaillant's Woodpecker Picus vaillantii and Great Spotted Woodpecker Dendrocopos major were associated with higher densities of snags and downed wood than foraging locations.Aims To quantify the nesting requirements of two sympatric woodpecker species in Tunisian oak forests.Methods We compared habitat structure around nests and foraging locations for both woodpecker species using logistic regression. We examined evidence for preferences in nesting substrates using resource selection indices. Then, we used discriminant function analysis to identify variables separating nesting, foraging, and unused habitat of each species.Results The probability of presence of nests of both species was significantly related to densities of downed wood and snags. Nests of Levaillant's Woodpecker were located in areas with slightly higher snag densities. Habitat structure differed between nesting and foraging locations of Great Spotted, but not Levaillant's WoodpeckerConclusion Both Levaillant's and Great Spotted Woodpecker showed high requirements for large-diameter trees and snags, which provide substrates for both nesting and foraging. Nesting habitat requirements may not always be higher than those associated with foraging, but the fact that they were for the Great Spotted Woodpecker calls for caution when planning for woodpecker conservation. © 2015 British Trust for Ornithology.
