Where Have All the Acorns Gone?

Nut-bearing trees in Pennsylvania and in parts of surrounding states have dropped few of the nuggets important to the survival of squirrels and mice, and a main diet of many other creatures, from turkeys to blue jays to deer.

Local residents have reported squirrels gnawing on plastic Adirondack chairs and devouring porch pumpkins.
