At first this guy was hanging around the high ground, now dry due to low water. He did look to be watching us go by.

Usually I take a shot and move on but here I watched just to see what he was up to.

He was doing the same, what is that ‘human’ doing. He swam over to the foot of the dike.

In this corner the dike has a slope down to the water, a path these guys use to go from one side to the other. He never had any intention of climbing up. It was a slow go over for a curious look.

Above is from a different angle.
Even in mating season you give them some room and a few interesting shots can be had.
