SHANGHAI spotted swans in its lakes for the first time in years and experts attributed the return of swans to wetland restoration efforts.
Officials from local wildlife protection stations found three adult swans and two cygnets in the Dalian Lake in the western suburbs of Shanghai when they conducted a routine bird observation, Shanghai Morning Post reported today.
Bo Shunqi, one official, said the five swans were searching for food in the corner of an abandoned pond and they flew away at the sight of people.
Records show that swans normally winter in tidal flats along the coast, such as the Dongtan wetland reserve on Chongming Island and the Jiuduansha wetlands in Nanhui, Pudong District.
It's still unclear why the flock appeared in the Dianshan Lake area further inland. A research is now under way.
Some people believe the Dalian Lake is rich in food supply and away from human activities. Others say that numerous wetlands in the middle and lower reaches of the Yangtze River have been destroyed or polluted, forcing swans to seek food elsewhere.
