First up is classic great blue. He (she?) just stands there doing nothing. Classic great blue is vaguely narcissistic, hoping passers-by will say “Ooo, awww, isn’t he (she?) beautiful?”
Next up is reflective great blue. This is a little bit like classic great blue in that he (she?) is doing that narcissistic posing thing. But don’t be fooled. Great blue has one eye on the water, hoping to catch sight of food.
