Hello, @roused. It's amazing and terrible. The baby cuckoo cannot keep its head but already understands that it must destroy other eggs. Where does this instinct come from?
Tell me, can you explain why you wrote that lately one wonders if perhaps the cuckoo should become the symbolic bird of the EU?
Yes it is a sad and amazing at the same time. The cuckoo even has a hump on its back in which the eggs fit snugly so it can more easily push them out. Some things are better left unsaid.
