Updated March 2020 Thanks to eBirders from around the world, the Macaulay Library now has media for more than 10,380 species—that’s 96.8% of the species on Earth! These recordings, photos, and videos are a powerful resource for research, education, and conservation. As we develop and expand Merlin Bird ID, Illustrated Checklists, and other useful applications, we want to fill in the gaps. Currently, we are missing photos of 405 species, including 184 that have been reported in eBird in the last ten years. Can you photograph a missing species? We have even more of a challenge with audio. Thanks to contributions from eBirders and sound recordists dating back decades, we have audio recordings for 9,380 species. This leaves 1,341 holes in our collection, 1,118 of which have been reported in eBird in the last ten years.
