via wikipediaOnce upon a time, a clutch of small eggs collected on the far Eastern Tundra in Russian were popped into a warm bag and taken on a ship to the UK. Whilst on the boat they were kept warm in an incubator where 13 little bedraggled birds hatched. Birds on the critically endangered list, the spoon-billed sandpiper. These 13 birds represent 5% of the worlds population, and they have now taken up residence, locally, at the Wildfowl & Wetlands Trust founded by Sir Peter Scott.
When the birds feathers turn red it indicates that they are in the breeding season, as featured below.
