Wild Willow Tit Population Collapse

Willow tit populations have collapsed in the UK, declining 90% since the 1970s - understanding causes enables targeted welfare conservation.

Key Facts

Willow tits have declined faster than any other UK woodland bird species
Loss of damp woodland with dead wood for nest cavity excavation is the primary cause
Willow tits excavate their own nest cavities - standard nest boxes are not used
Competition from blue and great tits for food resources has intensified as habitats change
Targeted damp woodland management with dead wood retention has shown local recovery

Welfare Considerations

Individual willow tits in remnant damp woodland populations depend on the specific dead wood resources needed for nest cavity excavation. Conservation management that retains and creates these conditions directly supports individual breeding pair welfare.

What You Can Do

Support woodland management projects that retain dead wood and damp woodland conditions
Report willow tit sightings to BTO monitoring schemes - every record matters for such a rare bird
Engage with RSPB and Wildlife Trusts managing woodland specifically for willow tits
