Last year on October 14, ornithologist Marcelo Barbosa uploaded an eBird checklist from a farm in northern Brazil with 20 species in all, including some manakins, an Amazonian Motmot, and photos and an audio recording of calls by a Yellow-browed Tody-Flycatcher.
With that, the Cornell Lab of Ornithology’s Macaulay Library of natural history media passed a milestone—2 million sound recordings in the archive, and counting. (Barbosa’s eBird checklist also included audio of a calling Black-throated Antbird and a singing Coraya Wren.)
Since eBird added the capability for birders to upload audio files to their eBird checklists in 2015, the Macaulay Library’s inventory of sound recordings has grown tenfold. The vast archive of bird sounds provides valuable data about species locations, ranges, behavior, and evolution for scientific research and conservation.
“This milestone is a mind-blowing community accomplishment,” says Mike Webster, director of the Macaulay Library, while noting that more than 38,000 audio recordists contributed to that milestone. “It inspires me to see so many birders sharing their recordings so that we all can enjoy, and study, the sounds of the birds of the world.”
