Homel is an ornithologist, award-winning international nature photojournalist, documentary film producer, birding tour leader and lecturer. He lives and works from his home within the magnificent Los Padres National Forest, California, USA (home of the California Condor) and from his second homes at Río Lagartos, surrounded by the magnificent Ría Lagartos National Park and Biosphere Reserve at the north tip of Mexico’s Yucatan Peninsula and El Tuito, near Puerto Vallarta, Jalisco, Mexico. A birder-naturalist since childhood, Greg founded Natural Elements Productions in 1986 and Natural Encounters Birding Tours shortly thereafter. Now he travels the globe on a full-time basis in search of rare and little-known birds and other wildlife. He shares his unbounded (and contagious) enthusiasm through excursions for small groups worldwide, and with a wider audience through state-of-the-art digital lectures, television, and wide variety of publications and video productions. Throughout his life, but especially since the early 1990s, Greg has guided, educated, and inspired travelers in over 80 countries throughout the world. His travels on all seven continents, from the Arctic Circle to the Antarctic and points between, have allowed him to see more than half of the planet's roughly 9,800+ bird species in their natural habitats. His early work appeared regularly in books and magazines, including Wildbird Magazine, The Audubon Society Field Guides to Eastern Birds and The Audubon Society Field Guides to Western Birds, Time, Birder's World, Tucson Lifestyle, and Texas Monthly magazines. Since the "digital revolution," Greg has moved into television, video production for conservation groups such as American Bird Conservancy, field guide writing and lecturing aboard expedition ships with the hope of "giving a voice to his truest love, which is the natural world and its inhabitants, especially birds!"
