Alpine avifauna versus climate and land-use change: ring ouzel in timberline ecosystem
Montane bird species have been less studied compared to species of other ecosystems such as farmland, mainly because populations appeared to be stable. However, there is growing awareness that many boreo-alpine species are also declining or will decrease in the coming decades, as they appear particularly vulnerable to climate change. Another threat for alpine birds are the current land-use changes that occur at these altitudes, and that could amplify the effects of climate change. In this context, the recent decline of the ring ouzel Turdus torquatus alpestris in Switzerland is particularly troubling. In order to understand what could be the main causes of this decline, we are willing to caracterize the fine-scale associations between the ring ouzel and its timberline ecosystem. To do so, we performed a telemetry-based habitat selection study during a whole breeding season in Valais. Our particular aim is to identify key features of the foraging habitat, which are likely to constrain resource acquisition.
