In addition, whether budgerigars can talk or not depends on their living environment and parenting style. If budgerigar lives in a stimulating environment, it will have more opportunities to imitate language and tone, thus improving its ability to learn Chinese. If they interact with humans regularly and get proper training, they will also improve their vocal and learning abilities.
In a word, whether budgerigars can talk varies from person to person. If you want it to learn to speak, you need to provide it with appropriate training and stimulation, and praise and reward it for every step of progress.
