The Golden State Permits Targeting Extremely Hostile Mute Swans Starting Next Year

A recently passed regulation in California will permit the continuous culling of non-native swans starting next year. This move has been labeled as essential by some authorities to safeguard the state's dwindling wetlands and native waterfowl, while critics have criticized it as “unethical”.

Mute swans, valued as ornamental birds, have proliferated quickly across California, where conservation experts say they harm habitats and dominate native species.

New Legislation Places Mute Swans to Invasive Species List

Assembly Bill 764, enacted by California's governor earlier this month, adds mute swans on the list of invasive birds that can be targeted freely, joining the English sparrow and starling. The bill goes into effect on 1 January.

“The challenge is that their numbers have increased dramatically and they do a lot of harm to the wetlands,” stated a state information officer. “California has lost between 90 and 95% of its original wetlands, and these birds inhabit those wetlands and cause significant damage.”

These large waterfowl can change wetlands when they colonize areas where they have not historically existed.

Environmental Effects of Mute Swans

“Given their substantial physique, they do tend to eat large amounts of vegetation,” commented an bird expert. “They eat submerged plants, species that develop with its roots underwater, and they not only eat a lot of it, but they will tend to uproot it, so they’re damaging the bottom.”

“They really have the capacity to alter the nature of the wetland a lot, and in a way that will impact, not only the other birds, but for all kinds of other plants and animals,” the expert added.

Aggressive Behavior When Nesting

After they claim a territory, particularly in breeding season when they are protecting eggs or chicks, mute swans hostilely expel other birds that enter their feeding area.

“It’s comparable to taking a teenage athlete and putting him in the school yard at a junior high,” explained the biologist. “He’ll prevail in every encounter.”

According to a statement by the conservation agency, mute swans are not safeguarded under the federal wildlife statute since they were imported to North America in the mid-1800s.

Background and Introduction

The species are indigenous to northern and central Eurasia and were brought to the United States by individual collectors to be displayed in zoos, public parks, and on private estates. Certain birds got free accidentally, while some were set free on purpose.

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

Wildlife Challenges

According to a state official, the secondary risk to California’s native species, after habitat loss, is foreign wildlife.

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

Opposition and Criticism

Certain organizations backed the bill. A conservation nonprofit issued a announcement urging Californians to contact and email their representatives to fight the bill, which they called “unacceptable”.

“This is a last-ditch effort by a fading outdoor tradition to add another ‘bird to the bag’, and we won’t stand by and let it happen!,” states the announcement.

Physical Characteristics

• Mute swans eat up to eight pounds of vegetation per day
• They typically measure 25 to 30 pounds
• They may reach up to 5.5 feet in length
• Their wing width can reach nearly eight feet
• They have also caused serious injuries to children and pets

“When they have eggs or they have chicks, they are particularly territorial and perfectly capable of hurting a human,” a biologist noted.

“They will certainly attack, not only with their beak, but they’ll often extend their wings and hit with their wing joints at something they perceive as threatening their territory. They have the strength to breaking your wrist by whacking you.”

These swans are sometimes acquired in some states for aesthetic landscaping, to manage water plants, or to deter competing birds. In California, mute swans are classified as a controlled animal and cannot be brought in, moved, or kept without a authorization.
