Liu Ying recognizes her master. Just take the initiative to feed it. As long as it is not afraid of people, it will soon recognize its owner. When raising a willow warbler, you need to accompany it more, interact with it more, and cultivate feelings with it, otherwise the willow warbler will be afraid of its owner. After the willow oriole recognizes its master, it will respond to the master's call, and will also take the initiative to approach the master and respond to what the master says.

Performance of Liuying recognizing its owner:

1. Not afraid of being approached by its owner, and will not even run away when being touched.

2. Can ruminate. For birds, rumination is equivalent to sharing food, which is a sign of recognition. However, it is not easy to let it recognize its owner. It requires a certain amount of time and patience to accompany and feed it.
