Ah, the great Australia Kookaburra.

Until you’ve heard one of these birds sing in person, it’s hard to imagine the sound they make.

Many people describe their trill as laughing, and there’s even a famous song about it.

On the old gum tree-ee
Merry Merry King
Of the bush is he-ee
Laugh
Kookaburra, laugh
Kookaburra
Gay your life must be

That said, their sound isn’t quite a laugh … but take a listen to the video below to find out for yourself.
