Which has the biggest wingspan a swan or a red kite?

A swan generally has a larger wingspan than a red kite. For instance, the wingspan of a mute swan can reach up to 10 to 12 feet (3 to 3.6 meters), while the wingspan of a red kite typically ranges from 5.5 to 6.5 feet (1.7 to 2 meters). Therefore, swans are significantly larger in terms of wingspan compared to red kites.
