Will it be more noisy to keep two four-happy birds than to keep one that likes to call? In fact, the answer to this question is not absolute, because every bird has different personality and habits. Some four kinds of birds may be quiet, while others may like to sing.

Generally speaking, however, it may be easier to bark if you have two four birds than one. This is because birds are social animals, and they communicate and express their emotions by calling. When there are many birds together, they may interact with each other, resulting in more frequent calls.

If you want to reduce the number of times birds sing, you can try the following methods:

1. Provide enough food and water to ensure that the basic needs of birds are met, so that they will not cry because of hunger or thirst.

2. Give birds enough exercise space and toys, let them consume energy and physical strength, and reduce boredom and anxiety.

3. Give birds enough attention and interaction, make them feel safe and satisfied, and reduce their calls as a way to attract attention.
