        Corvid Caching

        Explore how corvids remember thousands of hidden food caches in this video from NOVA: Inside Animal Minds: Bird Genius. During autumn, island scrub jays scatter thousands of acorns in locations all over their territory. During the rest of the year, a scrub jay will recover about one-third of the 5,000 to 6,000 hidden acorns. Another type of corvid, Clark's nutcracker, may cache food in up to 10,000 locations. In addition to being able to remember the locations of thousands of caches, corvids have a sophisticated understanding of when to retrieve certain types of foods (such as worms, which rot over time).
