Danwei points to this front cover story in the local newspaper Star News. The headline above the story reads "The Death of the Swans":
The dead swans join a number of other animals discovered dead in Chinese waters over recent months — 16,000 dead pigs in just one river, for example, and more pigs and ducks dead in others.
The dead pigs have been linked to a clampdown on the illegal pork trade, but the dead swans remain a mystery. According to Danwei, the Star News reporter decided there were four possible conclusions: killed by other animals, poisoned by garbage, water pollution, or disease.
