Look who I flushed out from one of the planters!
P.S. Jacob Royer (thanks for the comment Jacob!) raised an interesting questions: are these creatures chipmunks or squirrels. I think they are baby squirrels. They look exactly as their daddy who was fooling around my garden, digging my flower beds and flirting with bushytail ladies.
I found this information at wisegeek.com: "A chipmunk can be identified by the five dark brown stripes that run from its head to its tail, which is often upright. A squirrel, meanwhile, has thirteen stripes in total that are also dark brown and run the length of its body. A squirrel does not, however, have stripes on its face. A chipmunk is also usually smaller than a squirrel. Chipmunks run quickly, with their tails straight in the air. A squirrel runs with its tail at a horizontal angle". Hmm, I remember seeing some squirrels with no stripes... Anyway, I'll try to watch the creatures, they might change the color. I'll also pay attention to how they hold their tails.
P.P.S. OK, here it is, a picture of a chipmunk. Found it in my 2008 folder. Now, we can see the difference!
