The Golden State Permits Culling of Extremely Hostile Mute Swans Commencing Next Year

A recently passed statute in California will allow the continuous killing of non-native swans beginning next year. This move has been called essential by some officials to safeguard the state's depleted wetlands and native waterfowl, while opponents have condemned it as “inhumane”.

The species, prized as ornamental birds, have proliferated quickly across California, where wildlife officials say they degrade habitats and forcefully push out native species.

New Legislation Adds Mute Swans to Invasive Species List

This legislation, signed into law by California's governor earlier this month, adds mute swans on the list of invasive birds that can be hunted with few restrictions, joining the English sparrow and starling. The bill becomes active on 1 January.

“The issue is that their numbers have increased dramatically and they do a lot of harm to the wetlands,” stated a wildlife department representative. “California has lost between 90 and 95% of its original wetlands, and these birds take over those wetlands and create extensive harm.”

Mute swans can transform wetlands when they colonize areas where they have not previously been.

Environmental Effects of Big Waterfowl

“Due to their large size, they do tend to eat large amounts of vegetation,” commented an avian biologist. “They eat aquatic vegetation, stuff that will grow with its roots underwater, and they not only consume it in volume, but they will tend to dig it up at the roots, so they’re disrupting the bottom.”

“They really have the potential to modify the ecosystem of the wetland significantly, and in a way that will change it for, not only the other birds, but for all kinds of other plants and animals,” the expert added.

Territorial Instincts When Nesting

When they secure a territory, especially during breeding season when they are defending eggs or chicks, mute swans aggressively chase away other birds that invade their territory.

“It’s similar to taking a 17-year-old high school student and putting him in the school yard at a elementary school,” noted the biologist. “He’ll prevail in every encounter.”

Per a statement by the fish and wildlife office, mute swans are not safeguarded under the federal wildlife statute since they were brought to North America in the mid-1800s.

Origin and History

Mute swans are originally from northern and central Eurasia and were imported to the United States by individual collectors to be displayed in zoos, public parks, and on private estates. Certain birds got free accidentally, while others were released on purpose.

“Among numerous residents, the idea that they’re not indigenous is sort of tenuous,” a biologist noted. “If it’s been around your whole life long, you think of that as native wildlife. They’ve been in North America for a considerable period.”

Conservation Concerns

According to a department spokesperson, the next biggest danger to California’s native species, after environmental destruction, is foreign wildlife.

“This is undoubtedly a problematic species, but now there’s at least a method to help manage it,” the representative stated.

Opposition and Criticism

Certain organizations endorsed the bill. An animal advocacy group published a statement encouraging Californians to contact and email their representatives to fight the bill, which they labeled “inhumane”.

“The move represents a final push by a fading outdoor tradition to add another ‘bird to the bag’, and we refuse to accept and let it happen!,” reads the declaration.

Biological Traits

• Mute swans consume as much as eight pounds of vegetation each day
• Their weight is 25 to 30 pounds
• They often attain up to 5.5 feet in length
• Their wing width can reach nearly eight feet
• Reports indicate serious injuries to young people and animals

“When they have eggs or they have chicks, they are extremely hostile and fully able to hurting a human,” a biologist noted.

“They will certainly attack, not only with their bill, but they’ll often extend their wings and flap the front edge at something they view as intruding on their territory. They have the strength to breaking your wrist by hitting you.”

The birds are still purchased in some states for ornamental use, to manage water plants, or to deter competing birds. In California, mute swans are classified as a restricted species and cannot be brought in, moved, or kept without a license.
