The Blue Heron is a protected nongame bird. There are substantial penalties to killing or even harming one including jail time and up to 20K in fines. And yes, I know your post was in jest but I like to be a wiseguy sometimes and I remember my father looking up the penalties. Not because he had plans to hurt it, but he did look into using a water gun to try and scare it away and decided he could buy a lot of koi for the penalty if it did get hurt. I learned a lot of fun words from my dad thanks to that heron over the course of my childhood.
