Ruff (bird) [SEP] Conservation status
Fossils from the Pleistocene suggest that this species bred further south in Europe in the cool periods between glaciations than it does now. Its sensitivity to changing climate as well as to water table levels and the speed of vegetation growth has led to suggestions that its range is affected by global warming, and the ruff might act as an indicator species for monitoring climate change. Potential threats to this species may also include outbreaks of diseases to which it is susceptible such as influenza, botulism and avian malaria.
