Whitethroats are summer migrants that breed in dense scrub and hedgerows, and have shown dramatic population fluctuations linked to drought on their Sahel wintering grounds.
Whitethroat welfare is affected by habitat quality on breeding grounds and conditions on wintering grounds. On UK breeding sites, loss of scrub and hedgerow through agricultural tidying and development reduces nesting opportunities. Management that retains diverse scrub structure with open ground adjacent for foraging provides optimal breeding welfare.
