The squirrels are fun to watch. They are either stashing food in tree branches or piling up cones (not many of those this year) (red squirrels), or industriously and determinedly burying all sorts of things all over the place (grey squirrels). No matter how often I see this sort of thing, and I have seen it countless hundreds of times, it still makes me smile and feel privileged to have a glimpse into the lives of another species. As well, the squirrels are making sure their winter nests are snug and secure. Every so often you can see a grey with a mouthful of leaves, or twigs, or even bits of plastic, heading up to add to their nests. Or, sometimes carrying material into tree cavities.

This red squirrel was bringing grass to a tree cavity in the Arboretum (but I decided to include it here anyway). In this photo, he looks like he is resting from his labours, before carrying on. Judging from the grass still hanging out of the cavity, he has a way to go yet.
