- It combines Creative Commons xeno-canto recordings with country filters, mnemonics, and confusable-bird comparisons.
Field notes
The project presents a geographic listening atlas rather than a general bird encyclopedia. Its homepage reports 1,237 species, 3,312 field recordings, coverage across 58 countries and six continents, and a weekly most-listened ranking refreshed hourly. The recordings are attributed to xeno-canto under Creative Commons, while the learning layer is described as using mnemonics and comparisons between confusable species.
