This is one of a family of three squirrels who often frequent our roof terrace. It's three floors up and they climb hand over hand up an aerial cable which goes up the side of the house, then along the guttering to get at the bird feeder which is suspended from the balustrade. When we put it there we thought it would be well out of the reach of the squirrels, but we we obviously underestimated their ingenuity ! Our bedroom is directly underneath the terrace and we're often woken by them running and jumping around above us.
