Heatstroke in birds: recognising the signs and reacting
Birds have no sweat glands: they regulate their temperature by speeding up their breathing and holding their wings away from the body to release heat. This system, efficient under normal conditions, quickly reaches its limits in a heatwave, especially if the cage is in the sun or poorly ventilated. The physiology of avian thermoregulation and the role of panting (gular flutter) are well described (research on Google Scholar). Our other care pointers are in the bird care and grooming section.
The warning signs
An overheating bird breathes with its beak open, pants, holds its wings markedly away from the body, sits hunched at the bottom of the cage or, conversely, seems agitated and then apathetic. These signs demand an immediate response: heatstroke can be fatal within a short time in such a small animal.
The moves that cool a bird down
Place the cage in the shade, away from windows and hot draughts, in the coolest room in the home. Offer fresh, regularly renewed water and a shallow bath: many birds happily cool off by bathing, as explained in our guide to the bird bath. A light misting with lukewarm water can help, without ever soaking the bird or hosing it down abruptly.
Preventing it through summer
Never place the cage behind glass in the sun, where the greenhouse effect sends the temperature up very fast. Ensure gentle ventilation without a direct draught, always keep clean water available, and watch the diet, avoiding the risky foods listed in our article on toxic foods for canaries. A damp cloth over part of the cage creates a cooler zone.
Frequently asked questions
Is a fan advisable?
Only if it does not blow directly on the bird: a direct draught causes abrupt chilling and stress. Favour a gentle circulation of room air.
Can I give iced water?
No, water that is too cold is a shock: offer cool but tempered water, renewed often.
Which species are most sensitive?
All cage species are concerned, but older, sick or overweight birds overheat faster.
