The most reliable field mark to distinguish the Cape Teal from the Red-billed Duck is the bill color: Cape Teal has a pale pinkish bill, while the Red-billed Duck has a bright red bill. Both species are similar in size and structure, but their plumage and habitat preferences offer additional clues.
