What you need to know
- Perch 2.0 is an upgraded open-source model from DeepMind that listens to nature and helps scientists track wildlife through sound.
- It can sift through endless audio recordings—birds, frogs, whales, even background human noise—and make sense of it faster than humans ever could.
- The first version already uncovered hidden bird populations and sped up conservation work in places like Hawaiʻi.
- The new version handles messy, overlapping sounds better and can even estimate numbers of animals calling, not just identify them.
