This good samaritan saves the bird from suffering a heatstroke! I didn't event think this was possible so I did a little research and found this info according to Petcha.com:
In the early stage of heatstroke, a bird will hold its wings out from its body and pant. It may appear anxious or agitated, or have a blank stare on its face. As the condition worsens, the panting will become very heavy, and the bird will rock back and forth on the perch and have a hard time keeping its balance. Eventually the bird will fall off the perch and begin to convulse. “If the bird is allowed to convulse, the convulsion will continue to drive the temperature up — even if the bird is brought out of the sun — because the body is working so hard during the convulsion,” Dr. Harrison said.
If the temperature is not brought down quickly, the bird will die or sustain permanent brain damage.
So this man definitely helped this little birdie out big time!
