Die Macaulay Library ist laut Eigenbeschreibung das älteste und grösste wissenschaftliche Archiv mit Audio- und Videoaufnahmen von Tieren (via Phil Bradley’s Weblog):
“The Macaulay Library is the world’s largest and oldest scientific archive of biodiversity audio and video. It’s mainly birdsong, and can be searched with the usual search box, or by category. It’s an excellent collection, based on my very limited understanding of the subject area and if you’ve an interest in the great outdoors, it’s worth a quick delve into.”
