Carl began bird watching in 1973 at the age of seven. His first foray onto the international scene was in 1980 with a trip to the Austrian Alps. Since then, he has travelled extensively in Europe and the USA with trips to Southeast Asia and Africa.
In 1991 Carl was part of a successful conservation expedition to Colombia which resulted in the discovery of the Choco Vireo and developed his love of the country. He has since spent the last 30 years travelling and guiding throughout Colombia; his first tour being back in 1995. His experience in Latin America also extends to Venezuela, Brazil and Costa Rica.
Carl is also an award-winning sports and wildlife photographer and runs local workshops on the subject.
