ENGLAND : England has a
parakeet problem. The colorful bird is enjoying a population
explosion in London suburbs, devouring seed from feeders, fighting
with native birds, and possibly threatening crops. No one knows why
the parakeets have flourished. Possible reasons include residents
putting out more food for them, planting berries they like to eat,
the death of a predator, or climate change. Or it could be simply
that once there are enough parakeets, it’s easier for them to find
mates, and they breed faster. In any case, the government is
keeping an eye on them lest they begin to ravage crops as they do
in India. “I was delighted when I first saw one in my yard, but
when you have a flock of 300, it’s a different matter,” said Dick
Hayden, a retiree volunteering to help take a census of London’s
parakeet population. “They eat all the berries. They ate all the
food from my feeder in one day; it was
ludicrous.”
