Discovered a Common Snapping Turtle digging an egg-laying nesting site in our front garden planting bed Thursday morning. She was about 15 inches long from the tip of her nose to the tip of her tail. About two hours later she was found at the top of the storm water drain in front of our home. After taking several photos (from a safe distance with a 100-400 mm telephoto lens) I was able to safely entice her into our blue recycling bin and carefully transport her to the nearby stream where, I suspect, she had emerged.
After speaking with a Maryland DNR representative, moving her to avoid potential confrontation with adults, children, pets, and street vehicular traffic was the prudent thing to do. She readily took to returning to her natural habitat in the CA open space woods. Be especially cautious if you come upon a snapping turtle; as they can stretch their flexible, very long necks extremely quickly and their bite is particularly strong!
