Moon bird pose is an advanced arm-balancing and leg-behind-the-head posture that requires strength in the arms and shoulders, as well as flexibility, particularly in the hips and legs.
In moon bird pose, one leg wraps under the arm and behind the neck, while the other leg extends to the sky. With the palms pressing into the ground alongside the hips, both arms straighten, lifting the body off the mat.
The pose is also known by its Sanskrit name, chakorasana. In Hindu mythology, the chakora is a bird that lives on the light beams from the moon.
