Laughing Kookaburras are the largest kingfishers in the world, and Blue-winged Kookaburras are not far behind. Their size and distinctive shape and posture make them easily recognisable; their comical and personable characters make them readily memorable. They are able to live in a wide variety of habitats, and adapt to living around humans relatively well. This cheerful familiarity has caused them to figure prominently in the psyches and folklores of all peoples who have inhabited Australia. Kookaburras live in family groups marked by the extremes of social behaviour. Whilst in the nest, chicks fight their siblings for dominance and food so aggressively that the smallest chick is often killed. In complete contrast, many adult kookaburras delay their own breeding in order to help their relatives raise young. Kookaburra: King of the Bush provides a complete overview of kookaburras and their unique place in Australian culture and natural history.
