Northern Diamond-backed Watersnake On A Log
I photographed this Northern Diamond-backed Watersnake at the Sequoyah National Wildlife Refuge in Oklahoma. It was on a log floating in the river and if you look close you can see a dragonfly on the log underneath the snake.
It is frequently found basking on branches over water, and when approached, it will quickly drop into the water and swim away.
This Watersnakes bite is known to be quite painful due to its sharp teeth meant to keep hold of slippery fish. Unfortunately, this defensive behavior is frequently misinterpreted as aggression and often leads to its being mistaken for the venomous Cottonmouth. (Source: Wikipedia)
How I Got The Shot - Northern Diamond-backed Watersnake
I was driving the tour road at the Sequoyah National Wildlife Refuge when I spotted this snake on a floating log. It was in the river past the Tuff boat ramp.
I had my Canon EOS 7D Mark II camera resting on a bean bag draped over the open window of my pickup. I was using a Canon EF 100 - 400 mm f/4.5-5.6L IS II lens. I was shooting in aperture priority mode (AV) with a shutter speed of 1/800 of a second at f8 and the ISO at 320. White Balance was set on auto. I was using single point, continuous auto focus with evaluative metering.
