Wild Sand Martin: Colony Support and Bank Management

Sand martins nest in river and quarry banks requiring conservation management to maintain colony sites and welfare.

Key Facts

UK sand martin numbers have fluctuated but are broadly stable at around 300,000 pairs
Bank erosion and quarry closure eliminate nest colonies, causing welfare disruption
Artificial sand martin banks installed at suitable sites rapidly attract nesting birds
Nest tunnel blocks with appropriate dimensions successfully support colony establishment

Welfare Considerations

Nest site loss causes breeding failure and colony abandonment with direct welfare costs to adult and chick birds. Artificial bank installation at suitable locations with appropriate drainage and dimensions is a proven, cost-effective welfare intervention.

What You Can Do

Support local wildlife trusts installing artificial sand martin nest banks
Report active sand martin colonies to county bird recording groups
Advocate for river bank management that retains natural sand martin nesting sites
