Tour Leader

David Ascanio, a Venezuelan birder and naturalist, has spent over 39 years guiding birding tours throughout his native country, Colombia, Brazil, Peru, Costa Rica, the Orinoco and Amazon River basins, Trinidad & Tobago, Suriname, the Guianas, the Dominican Republic, Puerto Rico, the Lesser Antilles, Cuba, Chile, and Panama. He is especially interested in bird vocalizations and has a private library containing voices of more than 70% of all the birds of Venezuela. David combines superb birding skills with an astonishing command of bird vocalizations. He has published a book for children about bird songs and coauthored the descriptions of two new species, the Rio Orinoco Spinetail and the Delta Amacuro Softtail. David has also published numerous papers about the birds of the llanos (plains), Orinoco River Island species, and the pan-tepui endemic species on which he has become an authority. He is the senior author of the Field Guide to the Birds of Venezuela (2017). David is an excellent communicator, has a great sense of humor, and is tireless in helping others find birds and wildlife. These traits have made him one of the most popular naturalists/guides in the Neotropics.

Scott Baker’s interest in wildlife began early on while growing up in the leafy, outer eastern suburbs of Melbourne which, although a highly urbanized environment, retained significant tracts of remnant natural woodland. It was here at the age of 11 that he got his first pair of binoculars and began what was to become a lifetime quest to identify all the birds in an ever-expanding neighborhood. By the age of 15 he was running weekly bird walks and talks and became a founding member of the very successful Yarran Dheran Junior Field Naturalists Club. In 1988 he was named the Nunawading Young Citizen of the Year in recognition of his contribution to natural history and conservation. Pursuing mutual interests in life science and fine art, Scott went on to hold various roles in business, education, and environmental consultancy. This has facilitated opportunities to explore the wild places and wildlife of Australia and beyond. In 30 plus years he has traveled extensively throughout the continent with a major focus on birds. He loves the rare and sometimes challenging, cryptic varieties but also shorebirds and seabirds, having spent many days at sea. To date he has recorded (and photographed) almost all of the regular and resident land birds and pelagic species likely in the country. Scott has a passion for wildlife, not just birds, and conducts studies and regular surveys for mammals, reptiles, and frogs. His fieldwork will often involve additional nocturnal spotlighting sessions, requiring late nights and early mornings to maximize the “tetrapod” options, when possible. Scott is a well-regarded member of the Australian birding community, a moderator on several birdwatching forums and rare bird committees, and, since 2017, has run birdwatching and nature tours within Australia and parts of southeast Asia. He currently resides in Victoria but frequently interstate or abroad.

Max Breckenridge was born in the UK, but has lived virtually his entire life in Sydney, Australia. At age 12, his passion for birds was fostered when his parents took him and his brother out of school for 10 weeks to travel across Australia. After completing high school in Sydney, Max drove solo from Darwin to Broome, birding all the way, and spent the next month volunteering at the world-renowned Broome Bird Observatory. Max completed a Bachelor of Biodiversity & Conservation at Macquarie University in 2018. He has birded across every state and almost every corner of the Australian landmass. He has an excellent eye, and especially ear, for Australian birds. Some of his birding exploits in Australia include two separate trips to the remote rainforests of Iron Range National Park on Queensland’s Cape York (including a fly-in-fly-out trip during the middle of the wet season, when he spent two weeks under a tarp in order to see some of the key migrants from Papua New Guinea). Max is at home birding in the Old World and has spent the last decade covering as much of it as possible. He is incredibly passionate about wildlife conservation. In addition to guiding, he has spent much of his spare time working for BirdLife Australia, monitoring and researching the critically endangered Regent Honeyeater, including working on several captive-releases of zoo-bred individuals. Max receives immense pleasure from birding and showing birds to others. He is currently living on Lake Macquarie, north of Sydney, with his partner, Fernanda.

Kevin Burke is originally from the Shenandoah Valley in Virginia. He grew up running around in the woods and trails of Shenandoah National Park. His family spent many summers camping and hiking in the park. One of Kevin’s favorite activities was jumping in the river and turning over every rock to see what was underneath. This eventually earned him the nickname “Hellgrammite Kid.” This early exposure to the natural world has vaulted into a lifelong obsession with the outdoors. Kevin was introduced to birding while spending summers in Rhode Island at his grandmother’s house. She would point out all the feeder birds and help him identify them. These early encounters helped foster a love for birds. An early Ornithology class at Hocking College in Ohio rekindled his love for birds. He has been birding every day since. He went on to get a Bachelor of Science in Ecotourism and Conservation Ecology from the University of Idaho. Kevin has been involved with leading bird trips in some capacity for almost 20 years. He has led birding trips all throughout the United States, Costa Rica, Ecuador, and the Dominican Republic. His birding journeys have also taken him to some spectacular locations such as Portugal, Colombia, The Bahamas, and Canada. This is truly a lifelong obsession. He currently resides with his family in Hendersonville, North Carolina. Kevin’s wife and two kids also enjoy birding. They have fun kayaking, hiking, and camping in the mountains that surround their home. One of their favorite activities is jumping on the paddle board and kayaks and leisurely floating the French Broad River near their house.

Herbert Byaruhanga’s passion for birding and nature was cultivated in the picturesque Rutoto Village, where as a child, he observed and fed eagles near his home. His love for wildlife led him to pursue professional training, and he quickly excelled as the top candidate in an intensive Nature Guide training program at Lake Mburo National Park. Recognizing his exceptional potential, Birdlife International sponsored Herbert to further his expertise in South Africa, where he became a certified trainer of bird guides for Uganda and the broader East African region. Herbert holds a Bachelor's Degree in Tourism Management from Makerere University, alongside numerous certificates and diplomas in tourism, guiding, and leadership. Herbert's contributions to Uganda’s birding community are unparalleled.

Brian Gibbons grew up in suburban Dallas where he began exploring the wild world in local creeks and parks. Chasing butterflies and any animal that was unfortunate enough to cross paths with the Gibbons boys occupied his childhood. A wooden bird feeder kit sparked a flame that was stoked by a gift of the Golden Guide and family camping trips to Texas state parks. Thirty years ago Brian attended two VENT camps for young birders. Birds are now his primary interest, but all things wild continue to captivate him. After college, Brian undertook a variety of field biology research jobs that have taken him to the Caribbean, the Bering Sea, and the land of the midnight sun, arctic Alaska. He enjoys working with kids, hoping to spark environmental awareness through birds. For many years Brian’s field research has involved bird banding. His most amazing recoveries were a female Wilson’s Warbler that had been banded in Alaska and was captured by Brian in Colorado, and a Sooty Tern that perished after a hurricane on the Texas coast; it had plied the Gulf of Mexico and the oceans of the world for 24 years. Brian’s recreational bird-seeking has taken him to Machu Picchu in Peru, the Great Wall in China, the plains of East Africa, and the Himalayas in Nepal. Brian leads birding trips in the United States, Central America, the Caribbean, and Europe. As well as being a fanatical birder, he loves capturing birds with photography. He lives in Tucson, Arizona with his wife, Lacrecia Johnson, and their son, Grayson.

Paul Greenfield grew up near New York City and became interested in birds as a child. He received his B.F.A. from Temple University, where he was a fine arts major at the Tyler School of Art. Since 1972, he has lived in Ecuador where his fascination for birds and art has culminated in the completion of 20 years of work illustrating The Birds of Ecuador (Cornell University Press, 2001), which he co-authored with Robert Ridgely. The Spanish version was published in 2006 and The Birds of Ecuador App was launched in 2018. Paul is also co-author of Birds of Western Ecuador, a Photographic Guide (Princeton University Press, 2016) with Nick Athanas. He has participated in the discovery of a number a new avian species to science and has painted several frontispiece illustrations of these newly described taxa. Paul is very involved in saving Ecuador’s avian diversity and important habitats through his involvement with various foundations, as well as working with and inspiring local governments and communities to get involved in the protection of “their” biodiversity as a pioneer and promoter of birding tourism throughout Ecuador. He was the lead author of Ecuador’s National Strategy of Bird Tourism (2006), and its Update (2010). He has been showing visitors the birds of this fascinating country for nearly five decades and has led many Ecuador bird tours. Paul and his wife, Martha, live in Quito.

Remigio (Remi) Grefa was born and raised along the shores of the Napo River in the tiny indigenous Kichwa community of Añangu, in the upper Amazon Basin of Ecuador. As a child of the rainforest, he developed a close tie with the rich biodiversity of the Amazonian jungle, but became especially interested in birds as a young boy when he noticed foreign visiting birdwatchers arriving at a nearby nature lodge. It was then that he promised himself that when he grew up he would learn the names of the local birds, in English. . . and he eventually did! Throughout his formative years, his community had embarked on a groundbreaking nature tourism project of their own—the building and co-management (and eventually outright ownership) of the fabulous Napo Wildlife Center—and by the time Remi graduated from high school he was ready to join the ranks of this incredible endeavor. He began working at the lodge from the ground up (odd jobs, dishwasher, laundry brigade, etc.); after a few months he was promoted to waiting tables, and after six months he became one of the lodge’s bartenders for a year-and-a-half. He then graduated to boatman, where he was the second canoe paddler for many, many birding groups, which gave him the perfect opportunity to receive hands-on apprenticeship in birding, as well as English. In 2009, he took a job as a waiter on the Manatee Amazon Explorer, a houseboat style vessel that cruises the country’s Napo and Aguarico rivers. He was eventually promoted again as an official birding and naturalist guide at Napo Wildlife Center by 2017 and continues to fill that role exceptionally to this day. Remi and his wife, Lola, along with their two daughters, Kayana and Wita, live in the parish of Dayuma, not far from the frontier town of Puerto Francisco de Orellana (more commonly known as “Coca”).
