Bird Treks - A Quality Birdwatching Tour Company

Birding Around the World 23 Years

Your Leaders

Chris Lotz recently became the owner and operator of Bird Treks, which now focuses on tours within the United States and Canada. Although he necessarily spends a lot of time in the office, he sometimes leads tours to Cuba and many other parts of the world, and co-leads some of the trips in the United States and Canada. Ever since he can remember, birds have been his absolute passion. Originally from South Africa where he did his PhD on sunbirds, Chris then spent 2.5 years in Wyoming doing research on hummingbirds. While he enjoys this work and occasionally still publishes research papers for fun, he finds it a lot more exciting to actually get out birding. Over the last 14 years, he has in fact spent a large portion of his time developing and guiding tours for his sister company Birding Ecotours, which concentrates on tours in the other six continents. Chris loves all birds, but enjoys the challenge of helping people to see more difficult species such as rails and owls. Chris and his wife Megan currently live in South Africa, but are spending more and more time in Ohio, where they may in fact move to in 2017.


Bob Schutsky and his wife Nancy founded BIRD TREKS in September 1994. Until recently Bob was the sole owner and operator of this birding tour company. Chris Lotz has now assumed many of these responsibilities, with Bob continuing to refine the itineraries, and lead many of the long-standing tours that focus on destinations in the United States and Canada. Bob has been an active birder for 45 years, and has birded throughout the United States, many parts of Canada, and much of the Western Hemisphere. He has co-led birding adventures to Kenya and Spain, and has led nearly 50 tours to Costa Rica. Although it is difficult to choose his most favorite North American destination, it certainly includes Adak Island Alaska, Churchill Manitoba, Southeast Arizona, and Dauphin Island Alabama. His birding career began in 1972 with an ornithology course at the University of Miami in Florida, from which he graduated with a Bachelor of Science in Biology. Much of his work for the next 20 years as an environmental consultant involved the identification, study, and censusing of birds. He recently completed a long-term shorebird migration survey on the lower Susquehanna River in Pennsylvania. He taught bird identification classes at several local schools and universities. In 1976 he initiated and still organizes the Southern Lancaster County, Pennsylvania Christmas Bird Count for the National Audubon Society. He wrote a bird column for the Lancaster, Pennsylvania Sunday News, and helped to coordinate, compile, and author the “Atlas of Breeding Birds in Pennsylvania”. He wrote portions of “A Guide to the Birds of Lancaster County, Pennsylvania” and held former Pennsylvania Big Year and Big Day records. Birds and the love of nature are his life pursuits, and Bob thrives on sharing his knowledge and enthusiasm with others. Bob and Nancy live on the shores of the lower Susquehanna River in Pennsylvania.


Geoff Carpentier Geoff’s interest in nature began when he was 13, when he would wander through the woods and countryside near his Canadian home in northern Ontario, learning about nature first hand. Educated at the University of Guelph in Ontario, Geoff studied zoology and biological sciences. Recently retired, he worked for more than 33 years with the Canadian Ministry of the Environment. In his spare time, he maintained an active personal life where he led nature trips and taught nature and pesticide courses at community colleges. He is a widely published author in nature and science magazines and books, writes a bi-weekly nature column, and worked as an interpretive guide in several national parks. Geoff’s latest triumph is the publication of his second book, “Antarctica – First Journey”, a resource guide for Antarctic travelers, honoring the 13 times he has visited that exotic continent. He has traveled the world, visiting approximately 75 countries on all seven continents, where he has shared time with Polar Bears, Amazonian snakes and piranhas, observed the private lives of lions, avoided riots in Venezuela, hiked the Andes, camped with Pademelons in Australia, walked with penguins, searched for endemics in Colombia, traversed the Northwest Passage, and canoed Ontario’s northern lakes. Being an expedition guide and interpretative leader helps him build on his lifelong passion for nature. He has led numerous tours to Antarctica, South Georgia, the Falklands, Taiwan, Svalbard, Russia, Alaska, Cuba, Borneo, Greenland, the Galapagos, Tanzania, and more. Join Geoff as he shares his knowledge of wild things and places, delivered with caring and thoughtful attention to you, his clients!

Dan Heathcote began birding as a child in Florida, going on his first Christmas Bird Count at the age of ten. Living near the coast, Dan was able to participate in many offshore birding trips, something that he still enjoys today. Travel for birding has taken Dan all across the United States. Outside the US, Dan has birded in Mexico, the Bahamas, the Dominican Republic, Venezuela, and England. Since leading his first birding tour in Florida at age 16, he has lead Bird Treks tours to Arizona, Texas, and Alaska. With his keen eye, he discovered the first United States record for Crescent-chested Warbler while birding in Fort Huachuca, Arizona in 1983. Dan added the first record for Chestnut-sided Warbler to the bird list for Yellowstone National Park in 1989. He lives in York, Pennsylvania with his wife Lori and children Cory and Amanda. Hummingbird gardening is one of Dan’s favorite pastimes, along with coaching baseball.
