Important Bird Area

The sign on this tree in State Game Land #232 reads, "Important Bird Area."  And yet there are Bud Lite cans strewn on the ground all around the base of the tree.  If the birds that frequent this spot are so damn important, how come they're drinking Bud Lite, and don't they have lesser birds to clean up their messes?  Of course, to give the birds the benefit of the doubt, there are places in Washington County where drinking any beer more exotic than a Yuengling could get you killed.
