You can see in this photograph why this Turtle is called the Three-toed Box Turtle. If you look close at the back foot you will see that it has three toes. I came across this Turtle at my place near the Ouachita National Forest here in Arkansas.
I read that in Arkansas, Three-toed Box Turtles were observed in grasslands in late spring, while in early spring, summer, and late fall they were found in forested areas. During dry times, they dig shallow burrows into leaf litter to conserve moisture. When water is available, these turtles soak for longer periods of time than any of the other subspecies.
Three-toed Box Turtle - Ouachita National Forest - Arkansas
I was out on a photo walk on my property July 10th here in Arkansas when I spotted this Turtle. I was lucky and it didn't close itself up in its shell when it saw me. I sat on the ground to get an eye level shot while it was walking. I had the sun behind me and I was a good distance from the Turtle so this helped to keep it from retreating into its shell. I was using my Canon EOS 7D Mark II camera and a Canon EF 100-400mm f/4.5-5.6L IS II lens with a Canon EF 1.4X III Telephoto Extender. Because I had the extender on I was shooting at ƒ/8.0 (When using the extender on a f/5.6 lens on this camera you are limited to the center autofocus point only at an f/8 maximum aperture). The shutter speed was at 1/1000 of a second with an ISO of 1000. I needed this fast shutter speed because the Turtle was moving fairly quick. I had the exposure mode set at manual with auto ISO and evaluative metering. White Balance was set on auto and I was using single point continuous autofocus.
