Large parrots recognize their owners. Parrots have high IQs and can identify and remember their owners. They can also understand their owners' instructions after training. However, if you want a large parrot to recognize its owner, it is best to raise it from a young age. It is difficult for an adult parrot to recognize its owner.

How to train a large parrot:

1. When the parrot is a young bird, you can use food to train the parrot. Put the food on your hand to feed the parrot. The owner can whistle. After a period of training, when the owner whistles, the parrot will actively fly to the owner's hand.

2. You can take large parrots out to play and relax more often, so that they can get close to nature. In a natural state, the parrot will relax and recognize its owner more quickly.

3. Parrots have a lively personality, so the owner should interact more with the parrot. You can say hello to the parrot every morning and talk to the parrot more often. This can well cultivate the relationship between the parrot and its owner.
