Wild Grasshopper Warbler Welfare and Decline

Grasshopper warblers produce a distinctive reeling song but have declined by 50% since the 1990s. Their welfare requires young scrub and rough grassland habitats increasingly lost in Britain.

Key Facts

Grasshopper warblers are named for their insect-like reeling song lasting minutes at a time
They are highly secretive, creeping through dense vegetation rather than flying
Populations declined significantly in the late 20th century across Britain
They winter in West Africa and are vulnerable to conditions along the migratory route

Welfare Considerations

Grasshopper warbler welfare requires dense, tussocky grassland and young scrub that is now rare in an agricultural landscape dominated by improved grass and arable crops. Agri-environment habitats specifically designed for this species support welfare.
