The branch bends and sways in the breeze, but remains stable enough to
stand on.  A tiny bird's nest sits on a small branch that juts off of this
one to the east, but that branch is not nearly stable enough to hold
anything heavier than the nest.  From this point on the branch, you can see
the forest floor far, FAR below you.  A fall from this height would be
fatal.  The branch continues south and back to the trunk of the tree to the
north.
