Apollo the Swallow and Chack the Blackbird meet in the garden as fledglings when they are both learning to fly. Apollo explains that he is practising flying to Africa — but Chack doesn't believe him. Chack tells Apollo that the blossom on his favourite tree will eventually turn into orange berries — Apollo doesn't believe him. But, with the inevitable turning of the seasons, both birds learn to believe the other — and cement their friendship forever.
