Imagine that we invented a translator device you can put in your ear and that can translate anything into understandable human language. Now imagine that you are in a forest, you put this device in your ear and turn it on; that's the first 20 seconds. The little device picks up any audible noise, and it tries to translate it real time. After the first 20 seconds, it successfully translates the bird chirping into english, and so basically you can hear and understand how the birds see the world.
