Cygnus falconeri is an extinct, very large swan known from Middle Pleistocene-aged deposits from Malta and Sicily.

Its dimensions are described as exceeding those of the living mute swan by one-third,[2] which would give a bill-to-tail length of about 190–210 cm (75–83 in) (based on 145–160 cm for C. olor[3]).

By comparison to the bones of living swans, it can be estimated that it weighed around 16 kg (35 lb) and had a wingspan of about 3 m (9.8 ft).

[7] The remains of the species are associated with the Elephas mnaidriensis faunal complex, and became extinct long before the arrival of people to Sicily and Malta.

[8] Its bones are exhibited at Għar Dalam museum in Birżebbuġa, Malta.
