The Great Blue Heron is a bird that you can't get too close to. As soon as the bird sees you, the bird will probably be flying away. So approach the bird very slowly, don't make any noise and don't make any big moves. If you're lucky enough to be close to the bird in your car, you can photograph the bird with no worry of the bird flying away. Sometimes, if you are really lucky, the bird will land near you and you will have some great photo opportunities.
