Ready to jump. The reds on the bird's legs play well with the green environment.
Well seen.
He might jump from there, Francois but more likely he would just lean forward and extend his neck to 2 1/2 times the length you see in the original image and make the stab. It's breeding season which makes them much easier to spot. Normally, in a setting like this, the Heron will pretty much just blend in with its surroundings which makes them formidable hunters. In this shooting sequence, he did make a jump.
