Alien menace or victim of xenophobia? The battle over Britain’s parakeets

By · Via The Guardian Environment · Published by Everything Blog

In short

Britain's wild parakeet population is largely composed of cold-tolerant Himalayan stock, allowing the Asian species to establish large urban roosts across the country. European research demonstrates that the thriving flocks harm indigenous wildlife while transmitting illnesses such as Newcastle disease and the human parasite Cryptosporidium. Controlling the species remains difficult, as an Oxford researcher calculated back in 2003 that stabilizing London's population alone would require a 30 percent annual cull. Although authorities dropped plans for a state-led cull due to expense and complexity, officials opened a public consultation in March regarding changes to the quarry list to permit…

We hopped the fence and picked our way through the gravestones. Above us now were the birds themselves, their kryptonite-green plumage, scab-red beaks, pearly black collars and trailing tail feathers unmistakable: Psittacula krameri, the ring-necked parakeet.

Hither Green cemetery hosts one of the city’s largest roosts. Every day at dusk, a sizeable chunk of London’s feral parakeet population returns here, to a specific line of poplars. They like to spend the night in the company of their own kind. We watched them come first in ones and twos, and then in larger chirrupping squadrons. Hundreds of them, and then thousands. At maximum capacity, the trees fizzed. Here was a pandemonium, a parakeet concourse. It gave the impression of community, greeting and conversation. “This,” my…
