How do you stimulate the wing muscle in a bird?

To stimulate the wing muscle in a bird, you can encourage flapping through exercise or play, such as using toys that promote movement. Additionally, providing an environment that encourages flight, like a spacious area for flying, can naturally stimulate these muscles. You might also consider incorporating training sessions that involve rewards for wing use, making the activity enjoyable for the bird. Regular interaction and enrichment are key to keeping their muscles active and healthy.
