Will A Red Squirrel Kill A Grey Squirrel. Who wins the feeder fight, the bigger gray squirrel or much smaller red squirrel? Greys don't actually kill reds themselves, as is commonly believed.
Read it but belive it.
Red squirrels (sciurus vulgaris) are native to britain and ireland, but they are under serious threat of extinction in these countries because of habitat loss while the greys are immune to the disease, squirrel pox outbreaks can kill up to 80 percent of a red squirrel population in an affected area. Then the grey squirrels came along from america and killed them into near extinction. Not only do grey squirrels displace red squirrels, they strip bark from trees. Grey squirrels, on the other hand, seemed to ignore the scent and carry on regardless.
