Welcome to my Photography Gallery. My name is John Sterling and I have been an active birder in California since 1971 (I started young!). My professional career has included many years as a staff avian ecologist at the Smithsonian Migratory Bird Center and as an environmental consultant in California. I am currently working on several research projects and international tours with Sterling Wildlife Biology--my new business. I hope you enjoy my photographs. As an independent biologist, I offer the following services: birding classes, guiding, environmental consulting, biological research and surveys, as well as selling photographs and natural history books.
