Atlantic puffins at dawn along the granite boulders that ring Eastern Egg Rock Island off the coast of Maine. These boulders provide critical nesting habitat for these puffins. In fact, this tiny island is home to the world's first restored seabird colony. Methods used here to encourage and support nesting have been replicated all over the world to help endangered and threatened seabirds. I photographed these puffins from a blind so as not to disturb them.

Behind the camouflage of the tall grass, Murani the lion ("murani" means warrior in Maa, the language of the Maasai) looks upon the plains of the Maasai Mara after sundown. Lions are masters of stealth hunting and mostly search for prey at night. Producing the "red-eye" effect can sometimes be a good thing. The catchlight in Murani's eyes was made with my camera's pop-up flash turned all the way down to avoid adding any light to the scene. The only goal of using the flash was to add the glow to his eyes.
