Sand Martin Colony Nest Disturbance Welfare

Sand martins nest colonially in sandy banks and riverbanks, with colonies vulnerable to disturbance, flood events and bank erosion.

Key Facts

UK sand martin population fluctuates due to Sahel drought mortality
Colonies of up to thousands of pairs nest in holes in sandy banks
Natural riverbank erosion destroys nests but creates new nesting habitat
Aggregate extraction pits provide artificial nesting habitat
Predation of nesting adults in colonies by birds of prey creates welfare stress

Welfare Considerations

Colony disturbance causes simultaneous flushing of many breeding birds exposing eggs and chicks to heat, cold or predation. Aggregate pit management in collaboration with sand martin conservation can ensure nest hole availability throughout the breeding season.

What You Can Do

Support quarry operators managing sand martin nesting habitat
Maintain distance from active sand martin colonies during breeding season
Report sand martin nesting at new sites to BTO BirdTrack
Advocate for riverbank management that retains natural sandy sections
