Blue jays are currently busy hoarding acorns. Whereas some birds and mammals store acorns in a single spot, such is not the case with blue jays. These handsome birds hide each acorn they gather in a separate spot throughout the territory they will occupy throughout the winter. It is hard to believe that a blue jay might bury an acorn it plucked from your lawn at a spot more than a mile away.
Since a single blue jay can hoard up to 107 acorns per day, you might wonder how in the world it remembers every spot where it has buried an acorn. The truth of the matter is it doesn’t. Studies have found that a blue jay only retrieves roughly a quarter of the acorns it stashes away each fall.
In other words, each day that a blue jay is collecting and hiding acorns it is potentially planting 75 acorns. Obviously, some of these acorns will rot; other critters will consume some of them. The rest could potentially germinate and develop into new oak trees.
One might say that blue jays are playing a key role in replanting our precious forests. Looking at it another way, a single blue jay plants vastly more trees than any of us in a week than most of us do in a lifetime.
