I often hear our cousins across-the-pond express their concerns about grey squirrels and how they contribute to deforestation, the predation and resulting decline of woodland birds and of red squirrels. My Dad lives in New Hampshire and during a recent visit I noticed that among the grey squirrels were red squirrels. I also noticed that the 2 red squirrels dominated his yard. They chattered incessantly and ran off the grey squirrels when they ventured too close. I did some checking and there is no closed season or limit on red squirrels in New Hampshire or Maine. It seems that their numbers are growing faster than the grey squirrel. I can assure all those across-the-pond that Maine and New Hampshire have lots of forest, woodland birds and red squirrels. You should take-heart, if red and grey can live together and thrive in New England, they can do the same in England.
