Cygnus falconeri explained

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,^[1] which would give a bill-to-tail length of about (based on 145–160 cm for C. olor^[2]). By comparison to the bones of living swans, it can be estimated that it weighed around and had a wingspan of about .^{[3] [4] [5]} Due to its size, it may have been flightless.^[6] 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.^[7] Its bones are exhibited at Għar Dalam museum in Birżebbuġa, Malta.
