Blue jays have been found to cache somewhere between 3,000-5,000 acorns each in one fall and will bury seeds up to 2 ½ miles from their original source; they can start a forest in their lifetime. Because of the birds’ habit of burying acorns over a wide area, 11 species of oak trees have become dependent on them for the dispersal of their acorns. It is thought that Blue Jays are the reason oak trees spread north so rapidly after the last glacial period. Video by Stacy Holcomb
