One of my favourite birds is the southern carmine bee-eaters. They migrate to Zimbabwe from August to November. When they flock to the trees on the river bank one could be forgiven for thinking Christmas has arrived early; they decorate the trees with their brilliant colours. I was delighted to see their distinctive entrance holes to the tunnels leading to their nests in one of the cliffs on the river’s edge. Incredibly, these beautiful little birds excavate tunnels that extend between one and two metres into the cliff. The nest at the end of each tunnel contains up to five eggs. The colony was busy and noisy, with the red and green birds flying back and forth chirping and twittering – chaos!
