Sand Martin Welfare in River Banks

Sand martins excavate nest burrows in soft sand and gravel riverbanks, facing welfare threats from bank erosion management and flood events.

Key Facts

Excavates nest tunnels up to 60cm deep in sandy banks
First swallow-family migrant to arrive in UK in spring
UK breeding population around 250,000 pairs
Colonial nester with colonies of hundreds of burrows
Highly dependent on insect availability near water

Welfare Considerations

Bank reinforcement and flood defence works can destroy entire nesting colonies. Artificial sand martin banks in wildlife reserves have been successful alternatives. Flash floods during the breeding season can fill burrows and drown chicks.

What You Can Do

Support creation of artificial sand martin banks
Advocate for sensitive riverbank management during breeding season
Donate to RSPB and Wildlife Trust wetland bird projects
