Hyperthermia (overheating)- Spray cool water on the feet and body. Rubbing alcohol can be applied to feet to facilitate cooling. Monitor condition. If condition is not resolving seek veterinary care.
The best way to treat a bird that has hyperthermia is to put the bird in shallow room temperature water (not too cold and not too warm) and let the bird's feet become wet or spray its feet with tepid water. By cooling the bird's feet this will cool the bird's circulation to the rest of its body.
A caged bird cannot fly freely in the air to cool itself when the weather is warm. We must remember that a pet bird is confined inside a metal cage which can conduct heat and this makes it even warmer than the environmental temperature. Never place a bird outside in a cage because the shade can change. What was a shady spot in the morning will later be directly under the sun's rays and the caged bird is confined so that it cannot seek a cool shady spot.
Observe him. If he appears to have signs of a seizure or acts lethargic, then you should have him examined and treated in person.
I don't advise placing your bird in alternating temperatures of cool and then warm. A bird's thermo-regulatory center is not as efficient as a human's and a bird can become sick if it is frequently having to adjust to various temperature changes. Most birds do well in a consistent temperature the same as you would (approximately 78 degrees F).
