This Cottonmouth (Water Moccasin) spotted me first while I was walking at the Sequoyah National Wildlife Refuge in Oklahoma. I was on one of the service roads. Visitors can walk these roads but you can’t drive on them. This road had water on both sides and this snake was getting ready to cross the road until I showed up. It never moved while I photographed it from different angles. After a few minutes, it turned and went back the way it came.

If you walk any of these roads at the Sequoyah National Wildlife Refuge be careful and not step on one of these snakes. These roads have tall grass on the sides and in the middle. They are also narrow and the snakes are difficult to see.

How I Got The Shot – Cottonmouth In Tall Grass

I was carrying my Canon EOS 7D Mark II camera using a BlackRapid Camera Strap. I had the Canon EF 100-400 mm f/4.5-5.6L IS II lens on the camera. This has been a great setup for me on my many photo walks. The strap makes it easy for me to pull the camera up for a quick shot.

I was shooting with a shutter speed of 1/500 of a second at f5.6. The ISO was at 1000. I would have liked the shutter speed to have been higher but the ISO was already higher than what I like with this camera. I had the exposure mode set at manual with auto ISO and evaluative metering. White Balance on auto. I was using single point, continuous auto focus. As soon as I spotted the snake I began photographing it. After I saw that it wasn’t moving I got lower and a little closer.
