In terms of bird behavior, what does the technique of "wobble" refer to?

The technique of "wobble" specifically refers to dropping the hand to prompt the bird to release its grip. This technique is often used when handling birds, especially those that are clinging or gripping too tightly. By wobbling the hand, the handler creates a sense of instability, which encourages the bird to let go and step onto a more secure perch or hand. This method ensures that the bird can be safely and gently transferred without causing stress or harm, facilitating better handling practices among bird owners and caretakers.

The other options, while relevant to bird behavior, focus on different aspects of interaction and handling that do not align with the technique known as "wobble."
