Well some of the poles are hidden behind peeple, but there are 18 visible poles (the front one on the right cannot be counted because person).

But, the poles and the eagles don't quite match up. There is a skew pole in the middle without an eagle on the left side, and a missing eagle on the fourth pole from the left on the right side. So I think some photoshopping has taken away some eagles, so that there are 17 to be counted along the top?
