You’re thinking of the Great Blue Heron. It can get confusing, there is the Great Blue, the Tricolor, and the Little Blue Heron. The Tricolor and the Little Blue are more into hunting crabs than chasing fish, the Great Blue even eats small gators. They hunt at different levels of the food chain. A Great Blue will tolerate a Tricolor or Little Blue around, but chase off a Great Egret that is hunting the same fish it is. Things can get even more confused when a Great Blue mates with a Great Egret, but that seems to be mostly a South Florida thing, along with hanging chads.
The Great Blue Heron is a little lighter, almost greyish. I really think I’ve seen Tricolors in S. Florida. In fact, I think one is in a stream behind my workplace. If I can pry the digital camera away from the wife I’ll try to get a photo.
Fort Pickens pier used to have a mascot, a blue heron that had a leg amputated after it became entangled in a net. Even with one leg that bird never wanted for anything.
I know this isn’t the same species, but thanks I haven’t thought of that bird in a long while.
