Known for gliding along local waterways with statuesque grace, the mute swan is rarely thought of as an environmental hazard. Wildlife experts in Connecticut say that mute swans, like these at Holly Pond in Stamford, devour shoreline vegetation, displace waterfowl and other creatures, and can even attack people. But wildlife experts say that the swan’s elegant facade conceals an ecological menace that devours shoreline vegetation, scares away other waterfowl and can even attack humans. The bird is now a target of a campaign to reduce its numbers in the state’s delicate coastline habitats. The leaders of the effort are conservationists, including the Connecticut Audubon Society, which in the coming months will intensify a campaign to urge state officials to control the swans’ population, which stands at about 1,100. ... Kathryn Burton, president of SaveOurSwans U.S.A., a nonprofit organization in East Lyme, Conn., said the group would actively oppose the Audubon campaign as well. “I’m not going to let it go,” Ms. Burton said. “They really don’t care about the birds. It’s just unjust.” Connecticut’s swan population has more than doubled in the last three decades. Mr. Bull said that one idea for reducing the number of swans was to disrupt the nesting birds’ eggs to limit reproduction, a tactic known as addling. He said the Audubon Society was not suggesting that any of the 1,100 swans in Connecticut be killed — though other states have taken that step. full story

Humans are far more of a threat to the environment than swans. There are only 1,100 mute swans in Connecticut, if the human population of the state were only 1,100 the humans would still have more of an environmental impact, especially if those humans were typical modern Americans.

Environmentalists wanted to kill of the cherry-headed conures in San Francisco, the monk parakeets are always under attack even though they are essentially a replacement species for the extinct Carolina parakeet. Even here in Arlington, the Friends of Spy Pond still hate the geese.

The Audubon society wants to get rid of swans, well in this world nothing should surprise me anymore. Sometimes things still do, but they shouldn't.
