A cold morning, starting to rain. A coot on the nest, brooding, unable to move to shelter without letting the eggs cool. Towards the edge of the nest, a large piece of paper, one side formed from what looked like foil.
It took a lot of manoeuvring, using the beak as its grip, and fighting against a breeze which was trying to snatch away the paper. But eventually the job was done. The bird could now snuggle down under its makeshift cover.
