Can birds overheat in the UK?

Yes. Cages in sunny windows, cars, or poorly ventilated rooms overheat quickly. Heat stress causes open-mouth breathing, wing drooping, and collapse.

How do I keep my bird cool in a heatwave?

Move cage away from direct sun, ensure airflow (fan not directly on bird), misting for species that tolerate it, fresh water for bathing, and avoid travel in heat.

Is open-mouth breathing normal in hot birds?

Birds may pant briefly when stressed, but sustained open-mouth breathing in heat indicates heat stress — reduce temperature and contact an avian vet if it continues.

Quick answer

Pet birds overheat when cages sit in direct sun or hot cars. Move to a shaded, ventilated room, offer fresh bath water, and watch for panting or drooping wings. Heat stress is an emergency — contact an avian vet if your bird does not improve quickly.

High-risk setups

According to the RSPCA and PDSA, pet birds overheat quickly when cages sit in direct sun, hot cars, or poorly ventilated rooms. Common setups to avoid:

Cages in bay windows or conservatories
Travel carriers in hot cars
Poor airflow with no shade
Sudden temperature spikes when curtains open

Cooling safely

Relocate cage to coolest room
Partial cover to create shade — ensure air still flows
Fresh water for drinking and shallow bathing
Lightly mist some species (check species guidance)
Avoid drafts directly on resting sick birds

Signs of heat stress

Sign	Meaning
Open-mouth breathing	Overheating or respiratory distress
Wings held away from body	Trying to lose heat
Lethargy, falling from perch	Urgent vet care
