A Midland Painted Turtle was found basking in Oxford County Ontario on November 23rd. A few hitchhikers (leeches) were taking full advantage of the Turtle’s slow movement in the wetland over the past few weeks. These leeches are aptly named “Smooth Turtle Leech”. Leeches are not generally detrimental, and will sometimes provide a good food source for turtles during the active season. Although turtles are quite hardy, and basking in 7° weather isn’t unheard of at certain times a year, though by late November the urge to bask is generally greatly reduced as the Turtles prepare for a long cold winter. Basking this late in the season can sometimes indicate illness or injury, though this Turtle had clear eyes and good fat reserves, with no visible issues.
