The Eurasian jay is the most colourful member of the crow family found across temperate Europe and Asia, instantly recognisable by its pinkish-brown plumage, black moustache, and brilliant electric-blue wing patches. As one of nature’s most important seed dispersers, a single jay can cache up to 5,000 acorns per autumn, memorising the location of hundreds of individual caches using spatial memory. Many of these forgotten caches germinate, making the jay one of the primary architects of oak forest regeneration across the Northern Hemisphere.
