Jonathan Rossouw

Jonathan Rossouw

Zegrahm & Eco Expeditions Director Jonathan Rossouw is a medical doctor by profession; however, his lifelong passion for wildlife led him to trade in his stethoscope for binoculars and take up a full-time career in the expedition travel industry. Since 1997 he has guided wildlife expeditions throughout the globe, and has gained experience with over 7000 bird species and 700 mammal species in the process. Jonathan has co-authored birding site guides to Southern Africa and Madagascar, and his guidebook Where to Watch Birds in Uganda is widely acclaimed as one of the finest site guides ever published. Jonathan is equally enthusiastic about mammals and coral reef fishes as he is with his specialties, birds and reptiles; indeed, he has an infectious curiosity and passion for all aspects of natural history. This serves him in good stead as he leads travelers on expeditions to all seven continents and scouts new destinations for Eco-Expeditions.

Mike Murphy

Mike Murphy

Mike was born on the Isle of Wight, England, and raised just a stone's throw from the once largest passenger ship terminal in the world. From there, his travels have taken him to most countries around the globe, where he has served as cruise director and expedition staff on both small and large luxury vessels. Mike's recreational scuba diving unintentionally led him to a career as a deep-sea commercial diver. He has dived in almost all of the world's seas. After ten years he left commercial diving to captain his own charter boat along the inland waters of British Columbia. Five years later he returned to cruise directing, sailing from the icy waters of Alaska and Antarctica to the emerald seas of the South Pacific and beyond. When he wasn't working, he sailed his own vessel extensively along the east coast of the United States and traversed the Indian Ocean from north to south. Mike also works as divemaster, taking divers to explore the underwater world of the Arctic and Antarctic, diving beneath ice-caps and icebergs.

Rich Pagen

Rich Pagen

Rich first became enthralled by the wonders of the natural world around the tide pools and forests of his native New York. Since then, he has embarked on a career in conservation biology that has ranged from teaching science and environmental awareness to teenagers from Los Angeles, to traveling the coast and river deltas of Alaska’s North Slope by Zodiac to reach remote wetlands where he monitored loon nests. After such field biology projects as surveys for mammalian carnivores in the mountains of California, bird migration monitoring in Canada, and a study of army-ant-following birds in the Peruvian Amazon, Rich was drawn back to the sea where he taught marine science and island ecology on Catalina Island in California for several years. He has also conducted shipboard surveys for marine mammals and seabirds, as well tagging studies of sea turtles and pelagic sharks.
