Redshank Welfare: Sentinel Birds of Salt Marshes and Estuaries

Redshanks are the alert, noisy wardens of UK salt marshes, but their welfare is under pressure from habitat loss, disturbance, and intensive grazing.

Key Facts

Redshanks are often called the 'sentinel of the marshes' for their alarm calls warning other birds
UK redshank populations declined by 23% between 1995 and 2018
Salt marsh is a critical breeding habitat but has been lost extensively to coastal development and sea-level rise
Breeding redshanks require tussocky vegetation for nest concealment and wet areas for chick feeding
Winter redshanks concentrate on estuaries and can number over 100,000 in the UK
Disturbance by humans and dogs causes repeated flight responses that deplete vital energy reserves

Welfare Considerations

Redshanks are highly sensitive to disturbance and this sensitivity, while adaptive against predators, creates significant welfare costs in human-dominated landscapes. Each alarm flight costs energy that must be recovered from food. On salt marshes with frequent recreational use, redshanks show reduced breeding density and poorer chick survival. Managed grazing that maintains tussock structure without over-compaction is critical for maintaining breeding welfare.

What You Can Do

Support salt marsh restoration and managed retreat projects
Keep dogs under control near estuarine habitats year-round
Advocate for coastal planning that protects salt marsh from development
Report redshank breeding activity to local wildlife trusts for monitoring
Support the British Trust for Ornithology's estuary monitoring programmes
