The escaping budgerigar cannot fly very far
Generally speaking, the tiger parrot has a poor sense of purpose and can only compare the environment around the house. Familiar with it, so after escaping, it won't fly too far, and mainly wanders around. If they don't fly far, the tiger parrot can even fly back on its own. But if they have flown far away, the chance of them looking back is slim. So after the tiger parrot escapes, you might as well look for it in the trees around your home.
