Burr acorns appear every two years. Burr acorns are large, and when they appear there are tons of them. In fact, when they appear, their acorn meat is available in such quantities that any animal that feeds on acorns would find it impossible to eat them all. Botanists call this masting. Overwhelming potential predators is one way to ensure the survival of the next generation.
(This acorn in particular was scooped up under a Burr oak on Austin’s East Side. See it fully clothed.)
