Camp Creature: The Painted Turtle

Raise your hand if you know the name of Camp Foley's Painted Turtle! Well, even if you didn't raise your hand our shout out, "MUNCHER!" no worries. Today, I'm going to share with you all the fun facts about Painted Turtles, a native turtle to our area.

First of all, let me tell you something super cool: Fossils show that the Painted Turtle existed 15 million years ago! Amazing! Also, the Painted Turtle is the most widespread native turtle of North America. It can be found from southern Canada to Louisiana and northern Mexico, from the Atlantic to the Pacific oceans. The most common place we see the Painted Turtle at Foley is over in Hidden Lake because it enjoys fresh waters with soft bottoms, shallow waters, slow-moving currents, basking sites and aquatic vegetation. Those factors make Hidden Lake the perfect home for the turtles.

There are actually four types of Painted Turtles:

  • Eastern Painted Turtle: This turtle ranges from five to seven inches long. It's upper shell is olive green to black and it may have a pale stripe down the middle with red markings. The segments of the shell have pale edges and occur in straight rows across its back. This segment pattern is unlike all other North American turtles.
  • Midland Painted Turtle: This turtle has a dark, symmetrical shadow in the center of its bottom shell that varies in size and prominence. It ranges from four to 10 inches long.
  • Southern Painted Turtle: This is the smallest of the Painted turtles - only four to six inches long. Its top shell has a red line running down the middle, and its bottom shall is tan.
  • Western Painted Turtle: This is the type of Painted Turtle we see in at camp, and the type of Painted Turtle that Muncher is. It's top shell has a mesh-like pattern of light lines. It's bottom shell has a large colored splotch that spreads to the edges and often has a red hue. The Western Painted Turtle can grow up to 10 inches long.

As a cold-blooded reptile, the Painted Turtle regulates its body temperature though its environment, notably by basking. All ages bask for warmth - sometimes groups up to 50 turtles can be seen basking together. At Hidden Lake, we often see the Painted Turtles basking on logs. The Painted Turtle will spend the night perched underwater to sleep, and will wake at sunrise to emerge from the water and bask for several hours. Once it's warm enough for activity, it will take to the water to forage. It repeats this cycle two to three times each day in the warmer months. In the winter, it hibernates. Fun fact: during hibernation the Painted Turtle does not breathe! If its surroundings allow, it may take in oxygen through its skin. 

Our Painted Turtle's, the Western Painted Turtle, diet changes seasonally. In the early summer, 60% of its diet is insects, by late summer 55% is plants. The Painted Turtle is the diet to a few predators though, so it must be careful! Painted Turtles are most vulnerable when they are young. Nests are frequently ransacked and the eggs are eaten by garter snakes, crows, chipmunks, squirrels, skunks, groundhogs, raccoon, badgers and fox. The small, bite-size hatchlings can fall pray to water bugs, bass, catfish, Snapping Turtles, snakes, herons, rice rats, weasels, muskats, minks and raccoon. As adults, the Painted Turtle is more protected with its shell, but they can fall prey to alligators, ospreys, crows, hawks, Bald Eagles and especially raccoon. 

Final Fun Fact: Painted Turtles can right themselves when they are flipped upside down!
