Atlantic walruses (Odobenus rosmarus rosmarus) swimming underwater.Cornell University has released online the world’s largest ever digital collection of animal and bird calls, an enormous archive of recordings dating back to 1929.

The online Macaulay Library archive at the Cornell Lab of Ornithology comprises nearly 150,000 digital audio recordings of about 9,000 species.

It took 12 years for archivists to digitise the analog audio recordings, which include sounds of walruses, whales, birds, primates, frogs and other animals recorded in the wild.
