The building of the El Silencio Dataset was supported by [Earth Species Project](https://www.earthspecies.org/), Experiment.com and Footprint Coalition under a Science Engine grant “AI for Interspecies Communication". Compiling these extensive datasets was a major undertaking, and we are very thankful to the many domain experts who helped to collect and manually annotate the data for this competition. Specifically, we would like to thank (institutions and individual contributors in alphabetic order):
