Common Cuckoo's primary color is gray, with one exception being her bright yellow eyes. Her shoulder-length hair starts as a dark gray which gradients to a medium and then light gray at the tips. She has three chunky bangs, with her center one a yellow and dark gray, representing the real life animal's beak. The wings on either side of her head are varying shades of dark gray, also like the real life bird.

Her clothes are fairly simple: the most noticeable garment is her azure-colored scarf. She dons a dark gray long-sleeved shirt with a light gray sweater vest on top. The vest has a pattern similar to a bird's breast feathers. Her leggings are a very light gray that fade to a white. Going against the gray theme, her sailor-style skirt is white and she also wears yellow Mary Janes.

The common cuckoo (Cuculus canorus) is a member of the cuckoo family of birds, Cuculidae, which also includes the roadrunners, the anis and the coucals. It is a relatively small bird, about 32–34 centimeters (13–13 in) long from bill to tail. They are typically gray in color but the females tend to have a pinkish tint to the underbelly bars and sides. Common cuckoos moult twice a year: a partial moult in summer and a complete moult in winter. This species is a widespread summer migrant to Europe and Asia, and winters in Africa.

Common cuckoos are brood parasites, which means it lays eggs in the nests of other bird species. This bird particularly favors the nests of dunnocks, meadow pipits, and reed warblers. Not only do the eggs look very similar to the eggs in the invaded nests, the adults are also mimics, specifically to the sparrowhawk. This technique allows the females to lay their eggs without being attacked.

The diet consists of insects, with hairy caterpillars, which are distasteful to many birds, being a specialty of preference.

It is a popular bird in folklore and culture, having been referenced by Aristotle, William Shakespeare, and Frederick Delius.
