Sanderling Welfare: Arctic Breeding and Climate Change Pressures

Sanderlings breed in the high Arctic and winter on sandy beaches worldwide, facing welfare challenges from climate-driven breeding habitat change and disturbance at winter feeding beaches.

Key Facts

Sanderlings breed on sparsely vegetated high Arctic tundra and winter on sandy beaches from UK to southern Africa
UK winter flocks can number thousands at favoured sandy beach locations
Climate change is altering snow cover and invertebrate emergence timing in Arctic breeding areas
Recreational disturbance from dogs and beach users repeatedly flushes sanderlings during critical winter feeding

Welfare Considerations

Sanderling welfare faces challenges at both ends of their migratory range. In the high Arctic, climate change alters breeding conditions and food availability. On sandy beaches during winter, repeated disturbance from dogs and recreation forces flight responses that burn energy during the critical period when body condition for spring migration must be maintained. Sanderlings feed in the wave wash zone — the highest-disturbance zone on any beach — making them inherently vulnerable to human presence. Managed disturbance-free sections of key beaches during winter months directly benefit sanderling welfare.

What You Can Do

Keep dogs on leads on beaches during winter months to reduce sanderling disturbance
Avoid running at or toward groups of feeding sanderlings on winter beaches
Support management of disturbance-free winter feeding zones at key sanderling beaches
Contribute sanderling counts to BTO WeBS surveys that track wintering shorebird populations
