Eye Of A Great Blue Heron

Great Blue Herons locate their food by sight. Its eyesight is about three times more detailed than ours. They can hunt day and night thanks to a high percentage of rod-type photoreceptors in their eyes that improve their night vision.

It is amazing that these birds can see through the glare and the surface motion of the water and be able to judge the preys exact location and angle of view.

How I Got The Shot - Great Blue Heron

I photographed this bird while driving the tour road at the Sequoyah National Wildlife Refuge in Oklahoma.

Once I spotted it I got as close as I could with my pickup by watching the Herons’ behavior to see if it was going to fly. I would stop and wait for the bird to relax and then I would get closer.

I got in a good spot and began photographing it. I got lucky with this one and it came close for this profile shot.

I had my camera resting on a bean bag draped over the open window of my pickup. I was using a Canon EOS 7D Mark II and 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 1/2500 of a second at f8 and the ISO at 800. I also had a -0.7 exposure value because the sun was bright. White Balance was set on auto. I was using single point, continuous auto focus with evaluative metering.
