A bird with a black and white plumage is perched on a wooden structure in a lush, green environment. The bird lifts its right leg and begins to bend its head downwards towards its leg. The bird continues to lower its head, bringing it closer to its leg. The bird's head is now almost touching its leg as it maintains this position. The bird's head is fully bent down, and it appears to be grooming or inspecting its leg.
