A raven in Germany plays with a twig: “All the corvid family - including crows, magpies and ravens - are very intelligent and like many intelligent creatures they learn and challenge themselves through play. At Slimbridge Wetland Centre we sometimes see whole gangs of crows using a stick for a game of tag. I’ve seen ravens flying upside down for no apparent reason, and I’ve even seen examples of raven leapfrog with a bird lying on its back whilst its mate repeatedly hops over it.”
