Dippers are unique songbirds that feed underwater in upland streams, and their welfare depends on water quality, invertebrate prey availability and suitable nesting sites near fast-flowing water.
Dipper welfare is inseparable from the health of their upland stream habitat. Acidification reduces the invertebrate prey they depend on; pollution disrupts their feeding. The historical recovery of dippers following acid rain reduction demonstrates the direct link between environmental policy and individual animal welfare. Continued clean water legislation and upland habitat management sustains these welfare gains.
