Effects of forest management practices in clearings on breeding performance of the Red-backed Shrike (Lanius collurio)

Abstract

The structure and quality of breeding habitats play an essential role for breeding success of individuals and thus, the viability of populations. Knowledge on habitat requirements can guide management practises to ensure optimal conditions for breeding. In this study, we investigate the effect of different habitat features and forest management strategies on the breeding performance of Red-backed Shrikes (Lanius collurio) breeding in Gribskov forest, Denmark. We found that the availability of available perches for hunting is the main predictor having a positive effect on number of breeding pairs and fledglings. It was also positively associated with the number of years that the clearing has been occupied by breeding pairs. Furthermore, clearings with grazing animals contained breeding pairs for more years than clearings without grazing, suggesting improved foraging conditions in clearings with low vegetation. Our results provide direct applications for forestry management for improving the conservation status of this species.
