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. He is the visionary founder of the Uganda Bird Guides Club, Uganda Safari Guides Association, and the Uganda Women Birders Club. In December 2023, he successfully organized the inaugural International Conference for Women Birders in Kampala and is actively preparing for the second edition in Costa Rica, scheduled for September 2025. Known affectionately as “The Father of Birding in Uganda,” Herbert has trained over 90% of the country’s bird guides, gaining him the nickname “Mr. Product Knowledge.” In 2001, Herbert established Bird Uganda Safaris, a premier birding and wildlife safari company. His extensive experience has made him a sought-after speaker at birding and conservation conferences worldwide, particularly at prominent birding festivals in the United States, where he is a regular guest speaker. Herbert’s expertise spans the East African region, where he continues to lead birding tours across Uganda, Kenya, Tanzania, and Rwanda, now supported by his sons, Mark Bankunda and Davis Rukundo, who are celebrated among Uganda’s top birding guides.

Rafael Galvez has been birding and illustrating birds since childhood, a dual passion that developed when his family moved from Peru to South Florida. Always with a sketchpad in hand, he has traveled throughout the U.S., Latin America, and Eurasia in pursuit of birds. He served several years as a board member of the BirdLife International affiliate in the Republic of Georgia, developing educational and conservation programs.  He gained knowledge of the Caucasus region while directing a series of records and documentary shorts on the ancient chants of the Georgian nation. During that period he also produced retrospective books and catalogs on the works of Russian realist painters. He has combined his love of art, education, and birds while collaborating in several publications, including a field guide to Raptors and Owls of Georgia (Caucasus), which he illustrated and coauthored. After working with raptor research along the Black Sea, he returned to South Florida to spearhead a new phase for the Florida Keys Hawkwatch migration monitoring project, where he has participated as director. As chair of citizen science and IBA monitoring at Tropical Audubon Society in Miami, he has reached out to underserved communities by providing opportunities for the greater appreciation of birds and Florida habitats. Currently, he lives in Homestead, spends much time in the Everglades, serves on the Florida Ornithological Society’s Records Committee, and is on the Leica Sport Optics Pro Staff. He loves sharing his passion for birds with audiences of all ages, and has been a guide and teacher for over 15 years.

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”).
