This episode is nuts! Like peanut butter and jelly, Blue Jays and oak trees go together - they have a fascinating relationship that plays out in our forests every fall. Jays (and many of their corvid relatives) collect boatloads of acorns and engage in a caching behavior called scatter hoarding. The extent to which oaks have evolved to rely on this behavior is startling, and in this episode, Bill and Steve (he's back!) pull back the curtain on the fascinating world of acorns and corvids, revealing why these two groups are MFEO (Made For Each Other).
