Naturalist/Certified Photo Instructor
José Calvo
Nicknamed “Indio” (Indian) because of his powers of observation and quiet nature, José has almost two decades of experience working as a naturalist and photography guide; as well as being recognized as an expert birder and nature photographer in Costa Rica. Costa Rica is rich in biodiversity — over 893 bird species have been recorded in the country. Since very young José spent all of his free time in the outdoors in the forest, where he soon fell in love with the birds. He particularly enjoys listening to their calls, and watching their behavior. Oddly enough, another one of Jose’s passions is science and technology, and because of this, he was among the first in Costa Rica to experiment with digital photography. As the technology quickly improved so did his love for it. He truly believes that nature photography is the perfect combination of both of his passions. José has guided extensively in Panama and is a certified naturalist with Costa Rica’s National Learning Institute (INA). Aside from birding, José has led general natural history trips for leading conservation and wildlife organizations, and has recently gained experience leading soft adventure and multi-sport trips for young adults and students. Recently, José particularly enjoyed leading a group of student volunteers working in a rural community. In the off-season, he works as a photographer and pursues his passion for people and wildlife photography. José has also worked as a Photo Instructor in the Galápagos aboard the National Geographic Endeavour , in the Amazon of Peru on the Delfin II , and in the Mediterranean aboard the Sea Cloud . He really looks forward to share the experience that he has gained in Central, South America and the Mediterranean with Lindblad-National Geographic guests, as well.
Naturalist
Dennis Cornejo
Dennis has spent more than half of his life working with Lindblad Expeditions. He first studied biology in the Sonoran Desert. It was his work with the Arizona-Sonora Desert Museum that brought him into contact with Sven Lindblad. Dennis was working with sea turtles in Mexico, desert tadpoles in southern Arizona and evaluating various legume trees for arid lands agriculture throughout the Sonoran Desert. Sven asked him if he would be interested in working on a ship as a naturalist in Baja California… a simple ‘yes’ turned out to be perhaps the most important decision he ever made! At first, life as a Lindblad naturalist, working during the winter while on break from university, exploring Baja California while guiding and lecturing, was a positive feedback loop for his academic goals. Spending time with guests, who possessed incredible amounts of life experience and enthusiasm, soon eroded Dennis’ dreams of a career in Academia. However, during this time he earned a master’s degree with a thesis on the reproductive strategies of Sonoran Desert toads and a PhD with a dissertation on the mechanical design and biogeography of columnar cacti (large cacti including the saguaro and the cardon). For almost 40 years Dennis has explored and learned with Lindblad. At first in the Sonoran Desert, then the temperate rainforest of Southeast Alaska, the topical rainforests of South America and Oceania and many, many other places: dry to wet, hot to cold. As his world experience increased, so did Dennis’ interests… from reptiles and amphibians, to flowering plants, insects and other invertebrate and lichens. He also worked for 15 years as an Undersea Specialist diving and making videos from Antarctica to Svalbard to Papua New Guinea. Now he is out of the water and on the tundra, so what next? With Lindblad Expeditions there is no limit with the whole world to choose from!
Naturalist/Certified Photo Instructor
David Cothran
David has worked for Lindblad Expeditions-National Geographic since 1993 on six continents and in over 65 countries. David is interested in many of the natural sciences, particularly ornithology, geology and marine biology; he most enjoys contrasting the broad perspectives provided by world travel with detailed investigations of local ecosystems on land and in the sea. David is an avid wildlife and landscape photographer and enjoys shooting with DSLRs, compact cameras and his iPhone. He particularly focuses on photography of wildlife in habitat, macro images of insects and abstracts images of patterns and textures. Before joining Lindblad-National Geographic, David worked as a staff field biologist and education coordinator at the Point Reyes Bird Observatory, an independent research institution in California. At PRBO David studied songbirds, seabirds, owls and elephant seals while overseeing a broad education program, which included classes for school-children, workshops for professional biologists and interpretation for the general public. His home, which is completely off the grid, is at the crest of the Siskiyou Mountains in southern Oregon. He received his Photo Instructor certification in a multi-day training workshop. Developed and taught by National Geographic and Lindblad Expeditions photographers, the workshop helped him develop additional insight and skills necessary to help you better understand your camera and the basics of composition — to better capture the moments at the heart of your expedition.
Naturalist
Bud Lehnhausen
Bud received an undergraduate degree in wildlife biology at Colorado State University. He then immediately went to Alaska where he worked and lived for 30 years. At the University of Alaska, Fairbanks, Bud studied wildlife biology and received a master's degree conducting research on four species of alcid seabird nesting on a remote island in the Gulf of Alaska. For a number of years he worked as a research biologist studying various fields, including moose/habitat relationships, songbird populations in relation to succession, tundra bird populations and migration, and woodpecker populations after natural forest fires. Since 1983, Bud has worked as a naturalist and expedition leader with Lindblad Expeditions-National Geographic. During these years he has traveled in the Arctic and Antarctic, temperate and tropical regions of Central and South America, Atlantic Ocean crossings, and the western South Pacific. These numerous voyages over the years have given him a chance to appreciate diversity of life and cultures which he finds fascinating. In addition to traveling, Bud is an avid natural history photographer and his wife writes children’s books on natural history illustrating them and using Bud’s photographs. Having built their own super-insulated house in Fairbanks over a 20 year period, in 2003 they relocated their family to northern Colorado. They are in the process of being owner/builders of a new energy efficient passive solar home in the foothills above Fort Collins.
Expedition Leader
Larry Prussin
Larry has been a naturalist for more than 50 years. His experience includes extensive work in environmental education in Ohio, Vermont and Yosemite National Park where he was program director for the Yosemite Institute. He has been a ranger at Mohican State Park, Lehman Caves National Monument, and Glacier Bay National Park where he first met up with Lindblad Expeditions–National Geographic in 1990. Since then he has traveled to every continent, from the tropics to both polar regions, rain forests to deserts, wilderness areas to sites of ancient civilizations to some of today's largest, most cosmopolitan cities. Being a naturalist enables Larry to combine his passion for natural history with his training as a teacher. While birds and their adaptations are Larry's first interest, he enjoys viewing the world from an ecological perspective, studying the interrelations among rocks, plants, animals and other elements that affect the biosphere.
Expedition Leader
Lucho Verdesoto
Born and raised in the tropical country of Ecuador, Lucho is a passionate naturalist that has been working for Lindblad Expeditions-National Geographic since 1998. With a marine biology background, he started as a naturalist in the Galápagos Islands in 1994. Since then, he has filled numerous roles with Lindblad-National Geographic, such as naturalist, undersea specialist and expedition leader in the Galápagos Islands, Costa Rica and Panama, and Baja California. Currently, Lucho spends much of the year traveling the world aboard the National Geographic Explorer. Working for Lindblad-National Geographic has given him the opportunity to explore remote locations from the Arctic to Antarctica and everything in between, while the opportunity to lead and explore the Amazon has only increased his passion for evolutionary biology and the understanding of how biological communities interact in such a complex ecosystem. During his time off, Lucho enjoys traveling and spending time getting to know the vast National Park system in Ecuador. Holding a dive master's license, he tries not to let a place pass without exploring the underwater ecosystem - he considers Antarctica to be the wildest place he has ever been able to dive! He also enjoys writing nature articles for a major newspaper in Ecuador, as he strongly believes that nature can only be protected when it is fully understood and appreciated by its inhabitants.
Naturalist/Certified Photo Instructor
Mike Greenfelder
Mike learned early on that the best way to escape Ohio was to become a marine biologist. During college at Wittenberg University he attended a semester at Duke University's Marine Lab — that time only confirmed his love for all things oceanic and maritime. After graduation, Mike promptly moved to Catalina Island in California where he taught marine biology to school kids. Since 1999, Mike has been working and traveling chasing his three loves: marine critters, photography, and birds. Before joining Lindblad Expeditions-National Geographic, Mike spent one and a half years as the resident biologist at the Jean-Michel Cousteau Fiji Islands Resort, a renowned vacation destination in the South Pacific. His days were filled with a great combination of guest education, research, environmental projects, and local school children education. Mike has also worked in the Amazon of Peru and Ecuador, the Pribilof Islands of Alaska, the cloud forest of Costa Rica, and the kelp forests of Victoria, Australia. When not working, Mike enjoys underwater photography, searching for endemic birds, and sunset chasing. He received his Photo Instructor certification in a multi-day training workshop. Developed and taught by National Geographic and Lindblad Expeditions photographers, the workshop helped him develop additional insight and skills necessary to help you better understand your camera and the basics of composition—to better capture the moments at the heart of your expedition.
