St Augustine Bird Looking for Minnows

From one of he books that I have, it shows this as a little Blue Heron. Just find it hard to believe that they would turn into one of the Great Blue Heron's. Or do they just stay, Little Blue Heron's?

Pretty cool feet - shows even better on black. Like that beak.

Great capture. I had no idea they change so much.

[Irene Marshall]

Great capture, does work well enlarged love the effect of the water.

@milaniet @btwebb @irene111 thanks all. Barbara, was hoping someone would validate what I said, but from one of the books I currently have, that's what it says.
