The image is a vintage-style illustration of a bird, likely a goat-sucker (also known as a nightjar), with a crab hovering above it. The bird is depicted in profile, with its wings partially spread and its beak open. It has dark brown plumage with small white spots scattered across its body. The bird's legs are thin and delicate, and its feet are grasping at the air. Above the bird, there is a small crab with long legs and pincers. The crab appears to be suspended in mid-air, as if it is about to land on the bird. The background is a pale cream color, and the illustration is done in a detailed, realistic style. At the bottom right corner, there is text identifying the bird as a 'Caprimulgus' and its common name as 'The Goat-sucker'. In the top right corner, there is a small 'T.S.' marking.
