Food cache
A concealed store of food. A few species, such a the Coal Tit Parus ater and the Jay Garrulus glandarius, are known to make such caches, Jays often burying considerable quantities of acorns. The birds are able to find at least some of this stored food, which presumably has survival value for them during periods of food shortage in winter.From Peter Weaver's Birdwatcher's Dictionary
