Acrocephalus arundinaceus

CH — Near Threatened

CH — Regular breeder

Like other reed warblers, the raucous great reed warbler lives and breeds in dense flooded reedbeds. It is dependent on the protection offered by this wetland habitat, which is now rare. It may be disturbed, in particular, by water sports enthusiasts during the summer — for example, by canoeists or stand-up paddleboarders encroaching on its refuge. As well as damaging the vegetation, they will startle any reed dwellers — especially birds, which fly off, leaving their nests and chicks behind.
