Ruthie's wildlife scientist parents are taking on a new challenge - saving the endangered red-tailed black-cockatoo. For Ruthie this means a lot of exciting firsts: living in a house, and not a bus, starting at a 'real' school, and the chance to make some friends. As always, Ruthie will be helping her parents with their work, but will it be enough to make a difference for these rare and beautiful birds? And what will Ruthie and her family find themselves up against this time?
