Wild Bird: Whitethroat Summer Welfare

Whitethroats are common summer visitors to UK scrubby habitats, with welfare linked to conditions on African wintering grounds and UK breeding sites.

Key Facts

Whitethroats winter in the Sahel zone south of the Sahara and are highly sensitive to Sahel drought
A major drought in 1968-69 caused a 77% population crash from which the species has largely recovered
UK populations breed in bramble, hawthorn scrub, and rank vegetation along field margins
Invertebrate food supply during chick rearing is critical for breeding success
The species has recovered well since the 1969 crash as Sahel conditions improved

Welfare Considerations

Whitethroat welfare demonstrates the connection between conditions at different points of the annual cycle. A catastrophic drought in the Sahel caused UK population collapse as birds died on the wintering grounds. The species' recovery following improved Sahel conditions shows that welfare at wintering sites is as important as breeding habitat. Climate change may create future Sahel conditions threatening this recovered population.
