I know they can cause damage but they are also such fun to watch, especially when you get two or three together.
Quite a lot of damage this year; perhaps the hot dry summer concentrated the sugars in the sap under the tree-bark. In their native America they are the favourite prey of more than a dozen different predators; here, foxes and domestic cats are their only enemies though word is spreading that in areas where the pine marten has returned, grey squirrel numbers have plummeted.
