Rosella bird

What a delight it has been to be privvy to the raising of the baby rosella which we have named 'Charlie' (it's a boy - males have the colourful markings, females are green). The young bird doesn't have developed tail feathers, and Charlie must first master scrambling up and down the tree. The mother comes to feed Charlie and he has to reach the mother, and then the mother moves so Charlie needs to scramble once again to find its way to his mother. Every so often Charlie flutters down to the ground and finds another tree to climb. We 'chat' to Charlie when we're out in the garden. He spends most of the day in the tree by himself. Do birds get lonely....?
