It’s the end of mating season and both Herons and photographers are familiar, and comfortable, with each other. The rookery here now has the Great Blue Herons getting closer than usual.
Above an adult walked away from the Cypress and brush towards another area of swamp. However there is a trail between them, and I was already standing there.
No eye contact when being too close gives the Herons a sense of comfort. I look away, they do the same (well, he glanced to me going by), and go on about their business.
If you find yourself closer than normal with a subject glance away ignoring them. As long as the animal introduced the distance it usually works.
A friend placed a good example on my Facebook page. The image is me looking out into a swamp, with a young Great Blue standing next to me. He made a joke, but I was purposely ignoring the juvenile, he had just taken a first flight.
note; I don’t do much on Facebook, more happening here.
