Curlew sandpipers make extraordinary migrations from Siberia to Africa, stopping briefly on UK coasts. Their welfare during these critical stopovers requires careful habitat management.
Curlew sandpiper welfare during UK stopovers centres on rapid refuelling for the Saharan crossing. Birds arriving in poor condition from Siberia face the double challenge of recovering from the journey north and accumulating fat for the journey south. Disturbance during feeding on key scrapes and pools prevents the rapid weight gain they need. The dependence on Arctic lemming cycles - high lemming years mean fewer predators, boosting shorebird breeding success - links curlew sandpiper welfare to distant ecosystem dynamics entirely beyond direct intervention.
