Bitterns and cottonmouths

It was early morning (about 0715) and the temperature was just about 70 F. A least bittern -- always an avian photographic nemesis for me -- had just flown across the gravel road and landed in a patch of cattails about 30 feet ahead of me. I slowed, not that I was walking all that fast anyway, and decided to sit and wait a while on the wet and grassy bank to see if the bird would emerge in a photographable position. It did. But hoping for something even better I waited longer.

As luck would have it, while waiting I noticed a slight disturbance in a patch of floating vegetation about 15 feet from shore. My interest shifted to the floating grasses. Was something really there or was the disturbance caused by a current? I watched. Yes, there definitely was something there and it was closer to shore now. Ah ha! A snake. A dark snake with vestiges of darker bands and of a fair girth. Oh, of course. A Florida cottonmouth, Agkistrodon piscivorous conanti.

The snake neared the shore, idled quietly in the shallows for a minute or two, then slowly emerged. It angled towards a sunny spot about 6 feet from me. Once there it stopped with its head bathed in the warming rays, and then with tongue flickering coiled ever so slowly. When I shifted positions to better angle the camera the snake made a fleeting defensive gape.

Once it settled, I stood, moved quietly up the hill, and left both bird and snake in peace. This was a fine way to begin the day.

Undisturbed by my presence the snake chose a sun-warmed basking spot: My moving to take a photo prompted this half-hearted defensive display:
