The bird looks quite plain and unattractive when hiding in the trees and almost looks completely black. It's only when it comes into the open and there's enough light shining on it that you realise that it's a beautiful blue. It's song can be heard echoing throughout the forest. It sings when mist envelops the forest and it's song is haunting but beautiful to hear. If you've never heard it before, you could mistake it for a person whistling, yet it sounds quite different from a person. It's also called the naughty schoolboy bird or the whistling schoolboy bird.
