I have a lake in back of my house and I often place food at the waters edge to feed the birds and turtles. I am amazed at how the turtles can find the food on the bank of the lake within minutes. I see them (3-5) some 50 ft. out surfacing to look at the food site. they seem to take turns watching and come in when one after another turtle has eaten. When I walk to the glass door to look out, another 40 ft. from them they scatter. This seems to point out that they have an excellent sense of smell and vision.
