We've had a family of feeble minded squirrels around here for years. I've stood outside and watched one or more of them "Hide" pecans for winter. The lame brained critters will lay them on the ground and very carefully hunt and discard LEAVES to hide them under!! I keep finding them in my potted plants, in tree branches, on top of bird feeders,etc. I don't know how they find enough to keep well fed, but they look well fed and keep breeding new generations.
