Eurasian jay
Garrulus glandarius

— Where the name comes from
Garrulus is “chatterer”, from garrire: anyone who has heard its screech in a silent wood knows why. Glandarius comes from glans, the acorn, and says the rest — the Italian name translates exactly the second half of the binomial. It is a crow dressed as an exotic bird, with a patch of blue feathers barred with black that in the Middle Ages were used to tie fishing flies.

— What sets it apart
It is the reason Europe has oaks. A single jay buries up to five thousand acorns in one autumn, one at a time, scattered over square kilometres, and forgets a share of them: those sprout far from the mother tree, which is the only way an oak can move. When the ice retreated, oaks marched up Europe at a speed no model could explain by acorns simply falling to the ground. The explanation had wings.
