Guuguuburra ~ the sound of human laughter
"Kookaburra" was taken from the Wiradjuri word that describes the bird's call. Kookaburra's job is to signal the sky gods to light the sun each morning. It's said that if you're alone when you hear a Kooka, it means someone is missing you and you should go and be with loved ones. If a Kooka laughs at a gathering, it's a reminder to appreciate those you think of with love.
They also kill snek.
