Create a 3D model of a Yelkouan shearwater (Puffinus yelkouan) standing on the ground. Focus on its slender body with dark brown and black plumage on the back and wings, and a white underside. The bird’s wings should be folded neatly against its body, and it has a sharp, slightly curved dark beak. Its face is pale with dark markings around the eyes. Emphasize the contrast between the dark upper plumage and the white belly, capturing the bird’s sleek, elegant form and fine feather texture
