On the heights

At one point only the birds were flying
  and the winds came
took the wings
  at one point my neck hurt
for following the flight of birds
  then the birds got tired
and they glared in the eyes
  from anyone who saw them fly
at a certain point the planes appeared
  and cut off the wings of the birds
crossed the birds' routes
  at that time only planes flew
because the birds
  they didn’t have a license to fly
at those heights...
