Reactions if the budgerigar likes you:

1. The most obvious sign that the budgerigar trusts you is that it will take the initiative to get close to you. If you put food in your hand outside the cage, they will fly to the owner's hand to eat.

2. In the cage, it will be very excited when seeing the owner come home, and will jump around in the cage and make sweet chirping sounds. You call them and they will be answered.

3. If the budgerigar does not reject your touch, does not bite you when you pet it, and licks your hands from time to time, it means that it likes you very much. Otherwise, it will resist your touch and may even bite to show resistance.

4. Budgies don’t like bathing, so they usually put a basin of water in it to let it play by itself. But if you give a budgerigar a bath yourself and it doesn't resist, it means it really likes you and can even tolerate things you don't like.

5. If a budgerigar likes you, it will like to be with you. No matter where you go, it will follow you. It is full of curiosity about you and wants to see what you are doing.
