Wild Sand Martin Colony Conservation

Sand martins nest colonially in earth banks beside rivers and quarry faces. Colony welfare depends on suitable nesting bank availability, food supply and protection from disturbance.

Key Facts

Sand martins arrive from sub-Saharan Africa in March and April to breed in existing bank colonies
Colony sites are fidelity to and can persist at the same location for decades
River bank erosion and quarry restoration regularly destroy established colonies
Artificial sand martin banks made from sand-filled pipes have enabled colony establishment on new sites
Drought in the Sahel affects sand martin survival during migration and wintering

Welfare Considerations

Sand martin welfare depends on the availability of nesting banks and abundant insect food over water. Artificial bank provision has enabled welfare and conservation gains where natural banks are unavailable.

What You Can Do

Support construction of artificial sand martin banks at suitable wetland sites
Record sand martin colony size and breeding success through BTO surveys
Advocate for sensitive river bank management that retains natural nesting banks
