I often heard kookaburras laughing in the mornings when I woke. It is one of my favourite memories from my childhood in the bush. At common boundaries, kookaburras will have disputes with neighbouring kookaburra. Kookaburras from each group take it in turns to invade, and be chased
from, their neighbours’ patch. Laughing kookaburras have a lot of fun turning this into a ritual flying to and fro across the boundary in unison, passing each other in mid-air, turning the sky into a flying circus.
Kookaburras like to chorus to proclaim their territory. The more birds in a family group, the louder the cacophony and the stronger their territorial claim. Most birds drive their offspring from their territories when they are independent, but young kookaburras live at home for about four years helping to look after the next generation.
