Black swan turns up at British facility

DORSET, England, June 5 (UPI) -- Officials at a British swannery said they do not know how an Australian black swan ended up among the facility's 600 white swans.

Staff at the Abbotsbury Swannery in Dorset, England, said the appearance of the Cygnus atratus at the facility, which is home to 600 Mute swans, is a mystery, but they are intent on catching it because black swans are known to kill their young and the swannery is in the middle of hatching season, The Mirror reported Tuesday.

Workers at the swannery said they are on the lookout for a second black swan, as a mated pair would pose a threat to Britain's wildlife and environment.
