@hingehead,
There are already more parakeets in London than there are nightingales.
I've lived in London for over 60 years and have never seen or heard a nightingale.
Their recent population explosion is perhaps explained by a warmer climate, and by the spread of garden bird-feeders.
Perhaps !? Hardly a scientific explanation.How much did it cost us tax-payers for them to come up with that?Warmer climate? Have you seen my heating bills? Garden bird-feeders? These green fellas are twice the size of a normal bird-feeder and I don't recall Pets Are Us reporting a rush on bird-feeders over the past few years.
they probably escaped, and were released, from aviaries, pet shops and private homes.
There's that word again PROBABLY.Why would these aviaries,pet shops and private homes,all of a sudden,get rid of their unwanted feathered friends?
Flocks of bright green parrots that drown out traditional birdsong with piercing squawks
Tell that to the flocks of starlings which roost in the trees near me!
Some ornithologists fear the wider presence of parakeets could potentially spell disaster for a number of native birds, including owls, woodpeckers, and falcons.
Owls,woodpeckers and falcons.In London? I think not! Anyway,owls and falcons catch,kill and eat meat (of the rodent kind).Woodpeckers,as far as I know,eat grubs.These parrots are vegetarians.
"I've met people who've had their apple or pear orchards wrecked," Perrins said. "Damage is on a tiny scale at the moment, but that may not be the case when numbers go up to a hundred thousand."
When I see flocks of up to a hundred thousand even I will take cover!
One vineyard, for instance, was stripped only weeks before the grapes were to be harvested. Enough were left to produce just 500 bottles of wine instead of the several thousand forecast.
They must have used GPS to find one of the few vineyards in England.Anyway,they probably did us wine drinkers a favour.Have you tasted English wine? Yuck!!
In Barcelona, Spain, rose-ringed parakeets are now ranked the fourth most numerous bird.
Doesn't seem to have affected their wine production
It would be difficult to get rid of them anyway, because they retire into towns, where it's not so easy to pursue and shoot them.
Could do us Londoners a favour by booting out the flying rat that is the pigeon.
Please take the above comments with a pinch of salt
