On a Wing and a Prayer: The story of a Carnaby's cockatoo family introduces us to the amazing world of the Carnaby's cockatoo; one of five species of black cockatoo whose populations have declined dramatically. This is a story of love, loss and sheer endurance. Read about the parents' unique nest-selection behaviour, their elaborate courtship, and revel in the miracle of new life as the first chic breaks through the shell.
