Every spring, thousands of birds of prey cross the Strait of Gibraltar from Africa. Among the first to arrive is the black kite, which comes to breed on the peninsula and heads back south at the end of summer. It is one of the most abundant birds of prey in the world, and also one of the cleverest. It hunts, fishes, scavenges carrion… and turns its beak up at almost nothing. In Doñana, scientists discovered something surprising: the black kite decorates its nest with plastic and white rags. And it is not on a whim: the more decorated the nest, the stronger the pair that occupies it. It is a warning to other kites: this territory has an owner. And in Australia, it has been seen picking up burning branches to spread fires and hunt the animals fleeing from them. A neighbor in our skies with plenty of ingenuity.
