I just found this ---
For a long, long time, the chubby, chirpy house sparrow lived in our midst aplenty. Now, you can’t find them in the urban environment any more. All this has happened in a span of just a few years.
India is not the only place where the sparrows have disappeared from the cities.
In the Netherlands, they are already an endangered species. In Britain, their population is dropping at such an alarming rate that they are now in the red list as a species of ‘high conservation concern’.
In France, Germany, Italy, Belgium, the Czech Republic and Finland, the story is not very different.
This is an environmental alarm bell at its loudest.
House Sparrow (Passer domesticus) is a common bird that millenniums ago originated in the Mediterranean and came into Europe and Asia with the spread of agriculture. It was carried across the Atlantic in mid-19th century as a friend, to help clean up green inchworms from the trees of New York’s Central Park.
It was the most widely distributed species of the world.
Today it is suddenly disappearing in the urban environment. What this translates into is that the modern urbanization has reached a level where it can trigger the extinction of a species.http://www.inewsone.com/2011/03/19/wher ... -day/36737
I think tomorrow is House Sparrow day -- in India -- so just now there are some articles coming out from India about the decline of the House Sparrow.
Here they were just considered an invasive species so very little attention is paid to them.
