I photographed this porcupine in my own Alaskan backyard. The porcupine was hanging out in a small tree and I climbed up another tree with my 500mm lens just across from the critter. I wedged myself between some branches as I stabilized my big, heavy lens on another set of branches. I hit the motor drive just as the porcupine looked up. The sound of the motor drive so surprised this little guy that he almost fell off its branch, thus the startled look on its face which makes this image work. This image is included as the18th spread in my children’s book, “Once Upon Alaska”. Thank you for visiting.
