Osprey Winter Migration: Welfare on the African Flyway

Osprey migration to West African wintering grounds exposes individuals to significant mortality risks that conservation work is addressing.

Key Facts

Ospreys breeding in the UK winter primarily in West Africa, particularly Senegal, The Gambia, and Guinea-Bissau.
Young ospreys make their first migration entirely independently; natal site fidelity is high on return.
Satellite tracking has revealed individual migration routes and identified key stopover sites requiring protection.
Illegal shooting on Mediterranean migration routes causes osprey mortality that limits population recovery.
Wintering habitat — fish-rich coastal lagoons and river systems — is threatened by overfishing and development.
UK osprey populations have recovered from extinction through reintroduction and continue to expand.

Welfare Considerations

Individual osprey welfare during migration is challenged by a 6,000+ km journey that crosses hostile terrain including the Sahara Desert. Shot or injured birds suffer before death; individuals that make successful migration but find degraded wintering habitat face starvation. Protecting migration flyways requires international collaboration — protecting ospreys only on breeding grounds is insufficient if wintering and stopover habitats are lost.

What You Can Do

Support Osprey Leadership Foundation and Roy Dennis Wildlife Foundation conservation programmes.
Donate to organisations working to stop illegal raptor shooting on Mediterranean migration routes.
Report osprey sightings during migration to BTO BirdTrack to support flyway mapping.
Support international conservation organisations working in West Africa to protect wintering habitat.
