I hear lyrebirds in Australia mimic what sounds like human noises sometimes and it's weird.

It's rare and isn't as "spot on" as documentaries make it out to be, but when it happens it's always been when rock climbing in an area for most of the day and sometimes one comes along. They seem to pick up on the noises hikers and climbers make in those areas, which is mostly talking, laughing, cheering, etc. But like, it sounds nothing like another human, but you know that's what it's heard because it sounds like humans in the distance, just 10-20m away. Then they mix in random bird calls and it's fun to guess each bird it's trying to be.

It's kind of surreal; certainly interesting. Terrible distraction when you're supposed to be belaying someone who's halfway up a cliff 🤣
