Sloth

The Smallest Bird is Sloth.   While the others vied for power , Sloth could not be bothered.  He refused to grow in stature,  instead he honed his energy on escaping the carrion's glower.  In fact so tiny was his form  and so easily was he missed  he neither flew on his own wing  nor hunted his own grist.   He kept himself perfectly still  until the watcher's eye grew bored,   then slowly ever so  he would latch onto another  bird and ride as if a lord.  He was a trickster of another sort  using no slight of hand  It was by doing the very least that he took grew to take command. The toll of this was very high   and of course it brought him low .  He had no choice as to what he ate   nor where he chose to go . Too weak to hold himself aloft he was sure to someday tumble.  His body was too soft, his achievements too humble.
