In the autumn, it's common behaviour for some wildlife to create reserves of food - this behaviour is known as 'caching'! Coal tits prefer to cache food in particularly small, well-hidden places to reduce the likelihood of great tits stealing their reserves. Nuthatches will maintain their territories during Winter in order to defend their caches, and jays can collect thousands of acorns throughout Autumn. Crows, rooks and marsh tits are also among the many birds that cache food! #jay #rspb #naturefacts #discoverwildlife #earthinfocus #backyardbirding #wildlifefrommywindow #wildlifewednesday
