What is the issue of red and grey squirrels?

Hi all, im doing a graphics project about red and grey squirrels, and i currently know almost zilch about them. I was wondering if anyone knew any information about why Grey squirrels are considered to be the bad species, and what it is that they do to red squirrels to make them ';evil';. A link to an informative site would be helpful. Thankyou :)What is the issue of red and grey squirrels?
From my experience I have found that the red squirrel is more aggressive and will drive gray squirrels out of an area. They are smaller in size and are more timid than the gray squirrels. The red squirrel will live in hollows of trees and even in people's attics. Gray squirrels will make a nest either in a tree hollow or in the branches of a tree. I hope this helps.What is the issue of red and grey squirrels?
I believe that red squirrels were native to America. Some lady brought over grey squirrels, and many of the red squirrels were killed off. Supposedly, the red squirrels were a lot more docile, and the grey squirrels were more aggressive. This is one of the reasons you can't bring plants or animals into foreign countries without quarintining them.
I don't know much except that the red ones live mostly in really wooded areas and are not in the ';town'; areas. As far as the gray ones that live near me they are evil because they get in my garbage all the time, carry around food and leave it on the window sils and they try to get in my attic.





Sorry I couldn't be much more help but try google and the encyclepedia.
Grey squirrels came from America I think and the native red squirrels are being took over because the Grey squirrels take all of there food Research has shown that the answer may lie in the way each species uses the food available to them. It has already been mentioned that grey squirrels put on a lot more body fat than red squirrels which gives them a better chance of surviving. The larger, more robust grey wins in the competition for food and space and it is now widespread in England and Wales. It is more adaptable than the red squirrel and lives happily in hedgerow trees, parks and gardens as well as large woods and forests.
