Bird Call

The Butcherbird - surely one of the most virtuosic of our native songbirds. Listen here to some of their lyrical refrains. .
But what a ghastly name for a bird with such a glorious voice.
"Butcher" bird- apparently they earned the title because of their somewhat savage way of capturing and devouring their prey. Isn't life full of contradiction.
So what are they singing about?
What's their story?

The butcher comes early
warbling his signature tune...
