A trained falcon could catch food in the desert that no human could reach. Today, the falcon is a national symbol in Saudi Arabia and the UAE, and falconry is a beloved [[heritage]] — practiced with some very modern tools.',
      'The first change is tracking. A hunting falcon can fly kilometers away in minutes, and losing a trained bird — which can be worth as much as a car — was always the falconer\'s greatest fear. Now, falcons carry tiny GPS [[transmitters]] on their backs, lighter than a few coins. If the bird flies too far, the falconer follows it on a phone map, exactly like finding a lost phone.',

The drone lifts the lure high into the sky, and the falcon learns to climb and chase at heights that a human arm could never reach. Trainers say the birds become stronger and faster this way — the drone gives them a better [[workout]].',

      'Some people ask: does technology hurt the tradition? Most falconers say no — the heart of falconry is the [[bond]] between the human and the bird, built through months of patience.
