What's wrong with the colorful birds always open their mouths?

Colorful birds often open their mouths because they want to dissipate heat.This kind of bird may have heat stroke in summer, so you must put the bird cage in a cool place. At the same time, pay attention to ventilation. Good air circulation is important to the breathing of the birds.Daily feeding does not change much, but because summer feed is easy to be bad, one must be checked and replaced in time, and the water evaporates quickly.
