A large bird with a long beak and white feathers with black tips is standing on the ground in front of a lush green background. The bird begins to spread its wings wide, flapping them in a rhythmic motion. The bird continues to flap its wings, moving them up and down and side to side. The bird's wings reach their maximum span as it continues to flap them. The bird starts to slow down its wing flapping, bringing its wings closer together.
