Dunlin are among the most numerous waders in the UK but face significant welfare challenges from climate-driven changes to breeding and wintering habitats.
Dunlin breeding on drying upland habitat experience reduced invertebrate availability for chick feeding, leading to starvation of young. Adults on degraded moorland expend more energy foraging for adequate food. Wintering birds on estuaries face increasing disturbance and habitat loss from coastal development and rising seas. Individual welfare costs from chronic food stress, failed breeding, and habitat loss are distributed across millions of individuals in a declining population.
