What is the old mouth that is always opening up?

Grass birds often open their mouths because they want to dissipate heat.It is best to put this bird in a cool and ventilated place in summer. Do not hang the bird cage under the sun. High temperature will affect its health. If you cover the cage cloth, it may be hypoxic.Dowry it out of the food that is not eaten every day, and the water should be changed. Usually, pay attention to check to see that it is less water when drinking water.In addition, you can take a bath once a day and dry it as soon as possible after washing.
