The ancient world teemed with birds
Are birds actually so scarce elsewhere in the world? My experience in a small city on the east coast of Australia is that birds are everywhere and in great variety. On a recent morning, I counted 10 different species of bird walking 500m to the shops and back. And it is hard to ignore the noise from the large flocks of sulfur crested cockatoos and rainbow lorakeets that frequent my town.<p>I understand that what I see is already a pale comparison compared to 200 or 10,000 years ago, but the numbers are still impressive. I am also aware of how little attention my fellow citizens pay to the variety of bird life around them. But it is still surprising to me that people can talk about cities having few birds and little diversity.
