Heron's always look to me like some huge prehistoric flying creature. They're big, they fly rather slowly and they make it look like a lot of work. When I see one out of the corner of my eye I always suspect I've been thrown back in time which causes me to duck and hide in the bushes before it's razor sharp beak-teeth rip me to shreds, or before I'm run down by a rampaging Tyrannosaurus Rex.
Then I realize it's just a heron and I stand back up, brush off my knees, whistle nonchalantly and continue on down the road.
