Welfare of Wild Birds During Extreme Weather

Extreme weather events cause acute welfare emergencies for wild birds that increasingly need human mitigation.

Key Facts

Unseasonable cold kills millions of birds by depleting energy reserves
Extreme heat causes hyperthermia in nesting birds with limited shade
Severe storms kill migrating birds disoriented by lightning and rain
Climate change is increasing the frequency of extreme weather events affecting bird populations

Welfare Considerations

Wild bird welfare during extreme weather events represents an intersection of natural and climate-driven suffering. Cold snaps kill birds whose energy reserves are depleted, particularly insectivores whose food supply disappears. Heatwaves cause nest failure as incubating parents and chicks overheat. Severe storms disrupt migration and kill disoriented birds. Individual humans providing food, water, and shelter during weather emergencies provide welfare relief to garden birds. At larger scales, habitat management that provides shelter and natural food reduces bird vulnerability to extreme events.

What You Can Do

Provide food and fresh water during extreme weather events for garden birds
Maintain natural vegetation that provides shelter during weather extremes
Report unusual bird mortality events to wildlife authorities
Support climate action as the most effective long-term bird welfare intervention for extreme weather
