Clark's Nutcracker

• It can bury more than thirty thousand pine seeds in a single autumn, spread across thousands of caches kilometres apart, and recover most of them months later beneath a metre of snow, guided by landmarks.
• It has a sublingual pouch, a cavity beneath the tongue unique to its genus, in which it carries as many as a hundred pine seeds at once over several kilometres.
• The whitebark pine depends almost entirely on it to reproduce: its seeds do not fly, and without the nutcracker's forgotten caches that high-altitude forest would not regenerate.
