Snipers to protect Sydney’s penguins

Night watch on endangered species in Australia after nine birds mauled to death

Fox attacks on endangered penguins have led Australia’s wildlife authorities to post snipers at night to protect the birds.

A colony of about 120 little penguins (Eudyptula minor), also known as fairy penguins, at Quarantine beach in Sydney has recently lost about nine of its number to attacks. On Sunday night, the two snipers took their first watch but were unable to shoot the animals responsible.

“We’ve got infrared cameras as well to detect fox movements along with fox baiting … This is really a microcosm of the devastation foxes can wreak in some areas,” the National Parks and Wildlife Service told the Sydney Morning Herald.

Autopsies on the dead penguins showed foxes or dogs were probably responsible because of the nature of the bite marks. DNA swabs were being analysed.

Angelika Treichler from local group Manly Environment Centre told the Herald the attacks were happening at dusk when the nocturnal penguins come ashore. She urged dog owners to keep their animals on leads.

Meanwhile, the snipers are there to stay. “We’ve had no luck so far finding what has done this so we’ll keep on trying,” the parks service said. “We’ll be there for as long as necessary.”

Previous vaccines contained weakened or inactive strains of disease-causing viruses or bacteria. These provoked recipients’ immune systems into producing the antibodies [...]
