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.
