I think they travel to find a nesting spot. We usually find a slider or red ear close to the house happily scooping out dirt to make hole. I found one waddling along the levy around the lagoon that is now in the Cattle Dog's territory. I put her back in the lagoon twice, found her out the 3rd time and watched her. She went right to a spot in tall grass and started digging. Sure enough, she laid a clutch of eggs, covered them and disappeared. I never did find out if she went back to the lagoon or went to our pond which is about 700 feet from the house. We've watched them do the same thing near the pond and have had to detour around them.Maybe they travel far to mate?
I need signs that say 'Turtle Maternity Ward.'
about 4 years ago we were in the timber and heard one of our dogs barking. Found her standing over a snapping turtle in the timber, about 300 feet from our smaller pond, yep, digging a nest.
At least the dog had enough sense NOT to mess with her.
