Wild Corncrake Habitat Loss and Conservation

The corncrake has undergone catastrophic population declines across Europe driven by agricultural intensification, making it one of the most urgent conservation priorities for grassland bird welfare.

Key Facts

Corncrake populations declined by over 90 percent in the UK during the 20th century due to early silage cutting
The species uses tall vegetation for nesting and shelter; mechanised mowing destroys nests and kills chicks
Remaining UK strongholds are in the Western Isles of Scotland and parts of Ireland
Males produce a distinctive rasping call used to attract females and defend territories
RSPB corncrake-friendly farming schemes have helped stabilise and slightly recover some populations
Corncrakes are migratory, spending winters in sub-Saharan Africa, facing additional threats along migration routes

Welfare Considerations

Agricultural mechanisation causes direct mortality of corncrake chicks and adults through mowing machinery, and destroys nesting attempts, causing reproductive failure and stress. Surviving birds in degraded habitats face food shortages and increased predation pressure. The combination of direct mortality and habitat loss means that individual bird welfare and population viability are both severely compromised. Agri-environment schemes that delay cutting dates, adopt corncrake-friendly mowing patterns (cutting from the centre outward), and maintain tall vegetation buffer zones have proven effective at reducing mortality.

What You Can Do

Support RSPB and BTO fundraising that directly funds corncrake-friendly farming payments to crofters
If farming grassland in corncrake areas, delay cutting until after August 1 and use outward-mowing patterns
Report corncrake sightings to BTO BirdTrack to support population monitoring
Advocate for continued funding of agri-environment schemes that make wildlife-friendly farming financially viable
