How can I find my brother flying away?

If the elder brother has a leg ring on his legs, there will be a chance to contact after others pick it up.Usually after it flys away, you can find it in the surrounding woods, which usually inhabit these places, which is more convenient for it to catch food.If you usually listen to sound training when feeding, you can also seduce it with sounds, such as blowing whistle before feeding, and the whistle can attract it.
