There's a big tree near where I live, with a hole in the trunk, and I found out yesterday that at least three squirrels live there! I was cycling past when I saw one jumping from another tree with a pine cone in its mouth and scampering along the branches to the hole, and I stopped to watch it. But the brakes on my bike squeaked, and they obviously didn't like that, because another squirrel came out of the hole to see what was happening, and a third one ran up the tree making threatening noises, came to the edge of a branch and glared at me until I went away.

So I came back later and left them some nuts. I hope they're all snuggled up warmly today, it's really cold and frosty outside! ^.^
