Nest-site selection and predation in Savi’s Warblers, Locustella luscinioides.

Summary, in English

Capsule: Savi’s Warblers preferred sites dominated by high and dense Juncus and Rubus with thick litter, and avoided pure reeds; predation was higher in sites with less litter.

Aim: To describe nest-site selection and identify which habitat and nest features influence predation risk.

Methods: Comparisons were made between habitat characteristics measured at nest-sites and random points, and between predated and successful nests.

Results: Total vegetation cover, litter thickness, habitat type, undergrowth height and undergrowth cover, which were higher or denser at nest-sites, were the most important variables influencing the distribution of Savi’s Warbler nests. Nests were most often predated in sites with low litter thickness.

Conclusion: Savi’s Warblers are dependent on the presence of dense low vegetation and litter for nesting, which should be maintained close to or within reed-beds for their benefit.
