Where are all the turtles? Last month the question was asked of me by a young girl who obviously knew we usually see many, many turtles basking in the sun on the logs near the pond’s edge. Not on this winter day though. My answer was, the turtles probably are buried in the mud at the bottom of the pond since the water is very cold in winter. We will see them again when the weather warms.
I worked as a naturalist for a few summers when I was in my 20’s and learned to follow up on questions asked by people on my nature walks. It was important for me to learn more about a topic so I could provide accurate information when asked again by someone on my next hike. So I did some reading about the red-eared slider. This semi-aquatic, freshwater turtle is often seen here and I no doubt will hear that question again.
So where did the turtles go? Turtles are cold-blooded animals not capable of generating body heat. When water is below 37 degrees Fahrenheit, the turtle slows down, is less active, and does bury itself only to rise to the surface as needed. Since it needs to drink water during this time it is not hibernation like we read about with bears, it is brumation. As a turtle brumates it can still move around, sleep underwater by resting on a pond’s bottom or float on the surface with an inflated throat as a floatation aid. Apparently a red-eared slider can survive in this cold water with no food for 70 – 100 days. If water dries up, they will travel in search of more water.
The turtles are back! Red-eared turtles are semi-aquatic so we see them in water and on land. They eat aquatic vegetation and invertebrates, tadpoles and fish. We love seeing them on rocks and logs as they warm themselves in the sun. If there are not enough logs they will even stack upon one another. They communicate with each other through touch and vibrations. One could wonder what the “message” was between them all.
Want one as a pet? The red-eared slider is one of 3 North American Pond Sliders. While red-eared sliders live long in captivity, they are one of the most invasive species found on every continent, except Antarctica, due to people unfortunately releasing their turtle to the wild. If you want a turtle at home, know the rules and regulations which vary per state in keeping it as a pet. Plus know how to care for it through all seasons, especially knowing it could live with you for many years. Otherwise, enjoy your red-eared turtle sightings when you are outdoors!
