Wild Garden Warbler and Blackcap Welfare in Scrub Habitats

Garden warblers and blackcaps are summer migrants whose welfare depends on dense scrub habitats. Blackcaps have increasingly overwintered in Britain fed by garden feeders.

Key Facts

Blackcaps that overwinter in Britain come from central European populations not summer visitors
Garden feeders with soft fruits and fat maintain overwintering blackcaps through winter
Garden warbler populations have declined by 25% since the 1990s
Both species need dense shrub canopy for nest concealment and invertebrate foraging

Welfare Considerations

Blackcap welfare in winter is improved by provision of soft fruits, cheese and fat in garden feeders. Garden warbler welfare requires dense scrub management at the right structural stage for breeding in summer.

What You Can Do

Provide soft fruits and mild grated cheese for overwintering blackcaps
Plant native berry-bearing shrubs like elder and honeysuckle for warbler foraging
Submit blackcap winter records to BTO Garden BirdWatch to track population change
