Xeno-canto is a science project. It is a website where volunteers can upload sounds of animals. The name xeno-canto means "strange sound".
The website was started in 2005. In May 2015 Xeno-canto had collected some 243,000 recordings covering more than 9,300 bird species. By May 2025 the collection had grown to over a million recordings.
Xeno-canto is run by the Xeno-canto Foundation. It is supported and hosted by the Naturalis Biodiversity Center, a research center and museum of natural history located in Leiden, the Netherlands.
In November 2024, Xeno-canto added AvesEcho, an artificial intelligence algorithm. AvesEcho tries to identify European bird species from uploaded recordings.
By late 2024, the name Xeno-canto appeared in 5.000 scientific papers on Google Scholar.
