This is a vintage illustration of a bird catching an insect in mid-air. The bird, likely a goat-sucker (as indicated by the text at the bottom), is depicted in profile, with its beak wide open, attempting to catch a large, winged insect. The bird is primarily dark brown or black, with small, yellowish spots scattered across its breast and belly. Its wings are spread, revealing a lighter underside. The bird's tail is long and slightly forked. Its legs are thin and delicate, with small claws. The insect is a large, brown, winged creature, resembling a moth or a grasshopper. It is positioned directly in front of the bird's open beak, as if the bird is about to catch it. The background is a pale yellow or cream color, providing a neutral backdrop for the illustration. The style of the illustration is detailed and realistic, with careful attention paid to the anatomy of the bird and insect. The illustration is labeled with the bird's name, 'Caprimulgus, The Goat-sucker,' in elegant script at the bottom right corner. There is a small 'T.S.' in the top right corner.
