Anas crecca is a species of duck commonly known as the common teal, which is widely distributed across the Northern Hemisphere. Other synonyms for this species include the Eurasian teal, the green-winged teal, and the teal duck. The name "teal" is derived from the bird's blue-green coloration around the eye. These small dabbling ducks are easily identified by their size and distinctive plumage, with male birds displaying a chestnut head and greenish breast, while females have brownish-gray feathers. The common teal is a migratory bird that breeds in northern Europe and Asia, and spends the winter in southern Europe, Africa, and Asia.
