Watch as this Blue Jay fills its crop to the brim with peanuts on the Cornell FeederWatch cam. Did you know that Blue Jays store hidden caches, or stockpiles, of up to thousands of nuts (like acorns and hazelnuts) in the autumn months in preparation for winter? Besides providing a winter food supply, this behavior plays an important role in seed dispersal for many tree species!

This FeederWatch cam is located in the Treman Bird Feeding Garden at the Cornell Lab of Ornithology.
