UK Passerine Migrants: Welfare During Spring and Autumn Passage

Overview of welfare for migratory passerine birds during spring and autumn passage through the UK.

Key Facts

Millions of small migrants pass through the UK each spring and autumn
Weather hazards including storms and fog cause navigation difficulties and welfare harm
Garden habitats provide critical refuelling stops for passage migrants
Ringing stations contribute welfare data through population and condition monitoring
Migratory small birds face predation risk during migration that reduces welfare

Welfare Considerations

Migratory passerine welfare during passage through the UK depends on refuelling habitat availability, weather conditions, and predation risk. Gardens, woodland edges, and coastal scrub provide critical refuelling habitats. Weather events can trap migrating birds in exposed locations with welfare harm. Light pollution attracts and disorients nocturnal migrants with welfare costs. Supporting passage habitat and reducing light pollution are welfare actions accessible to individuals.

What You Can Do

Maintain garden habitat for passage migrants with appropriate food and shelter
Reduce artificial light pollution during peak migration periods in spring and autumn
Support bird observatories and ringing stations contributing to migration welfare science
