This is a vintage illustration of a brown booby bird. The bird is depicted in profile, standing on a rocky outcrop. It has a long, pointed beak and dark eyes. Its feathers are detailed with fine lines, giving a textured appearance. The bird's feet are webbed and appear strong, gripping the rock. Below the bird is a depiction of the ocean with a horizon line and a few small waves. Above the bird, in the upper left corner, is a detailed line drawing of the bird's head, showing the inside of its mouth and beak open. The background is a pale yellow, typical of antique illustrations. The illustration is labeled with the bird's name in Latin at the bottom.
