Shawn has been an avid birder since he was 8 years old and is excited to bring his knowledge, experience, and passion for birds and bird diversity to a new audience with Birds of the World project.
Peter started birding at a young age in his home country of Belgium. He soon birded all over Europe, and shared his bird knowledge by writing articles, co-authoring a book about the birds of Flanders and joining the Belgian Rarities Committee—all while completing his MSc in both Engineering sciences and Music. In the early 90s he moved to the Neotropics where he developed a special interest in bird sounds. He pioneered sharing bird song recordings by making multimedia productions and his MP3 collections were the reference for many Neotropical countries in the pre-internet days. Back in Belgium, he continues to focus on recording and studying bird sounds, and he has been especially prolific in analyzing bird vocalizations to support taxonomy and identification. Peter has written more than 1,000 voice accounts for Birds of the World, 400+ notes on the vocal distinctiveness of taxa, and several bird sound-related scientific papers. Peter’s entire bird sound collection – about 30,000+ recordings from about half the world’s bird species – are now all available at the Macaulay Library. He continues to provide expert voice accounts for Birds of the World.
