Every year at about this time, red squirrels can be seen nibbling at maple branches to get the sap running, which they then lap up. This little guy was so busy on a Manitoba maple that even though I was standing nearby, and he knew it, he kept on working. He ran up and down the various branches, hung upside down and contorted himself into all sorts of positions to get at the sap. Here, you can see his little pink tongue licking away.
