Wild Sand Martin River Bank Welfare

Sand martins are colonial breeders that excavate nest burrows in sandy riverbanks and cliffs, with their welfare dependent on stable breeding sites.

Key Facts

Sand martin colonies can number thousands of pairs in appropriate habitat
Bank erosion and bank stabilisation both threaten nest site availability
Nesting commences in late April and chicks fledge by late July
Artificial sand martin banks have been successfully used to supplement natural sites
Sand martins winter in sub-Saharan Africa and face threats throughout their range

Welfare Considerations

Sand martin chicks in burrows are vulnerable to bank collapse, flooding, and predation. Loss of natural sandy banks through river management and erosion reduces available nest sites, concentrating competition and increasing welfare risk. Artificial bank provision and river management sensitive to sand martin needs are key interventions.
