Background Connections between habitats are key to a full understanding of anthropic
impacts on ecosystems. Freshwater habitats are especially biodiverse, yet depend on
exchange with terrestrial habitats. White storks (Ciconia ciconia) are widespread
opportunists that often forage in landfills and then visit wetlands, among other habitats. It is
