Wild Cuckoo Migration Welfare

Cuckoos undertake remarkable migrations to West Africa, with welfare challenges from food scarcity and habitat loss along the route.

Key Facts

UK cuckoos have declined by over 65% since the 1980s
Satellite tracking has revealed cuckoo migration routes through sub-Saharan Africa
Drought in the Sahel affects survival during the critical wintering period
UK cuckoos parasitise mainly reed warbler, dunnock, and meadow pipit nests
Availability of large caterpillars, especially hairy tiger moth larvae, determines breeding success

Welfare Considerations

Cuckoo welfare spans the entire migration route from UK breeding grounds to African wintering areas. Sahel drought causes starvation. UK caterpillar prey decline reduces breeding success. The welfare of this charismatic species requires international conservation action across its entire range.
