Caught a pair of orioles, who always don't say why.

Panic and anxiety, inadaptability to the new environment, lack of food and water, and illness.

1, panic and anxiety: orioles are wild animals. After being captured and kept in an artificial environment, they will feel panic and anxiety, resulting in no barking.

2. Not adapted to the new environment: orioles live in the natural environment. After being captured and kept in captivity in the artificial environment, they need time to adapt to the new environment and keep quiet during the period.

3. Lack of food and water: If the orioles are not given enough food and water after being caught, their physical and living conditions can't be met, resulting in the inability to bark.

4, sick: Huang Wei will get sick after being arrested, which will make it impossible to scream.
