Sooty tern nests (2′)
The terns nest as close to one another as possible without getting in the range of each other’s beaks. This leads to equally spaced nesting places with almost mathematical precision.
Coming up: “Soon, in those nests behind me, eggs will start hatching. Most will produce young weaver birds, but some equally certainly, will be cuckoos. Whichever they are, the young chicks will be faced with a whole set of problems that they have to solve if they are to grow into adults. And the ingenious and sometimes touching way in which that is done is what we will be looking at in the next programme in The Life of Birds.“
