I agree, GBH and other herons are destructive and they are ruthless in their search for food; if they don't find a plentiful supply of fish at hand, they'll go for something else: frogs, newly-hatched goslings or ducklings or other small creatures. I think that probably one reason we never saw any ducklings on the lake this spring is that probably Alfred and his brethren opportunistically grabbed them and dined on them. Nature can be cruel at times!
Alfred also looks somewhat prehistoric, as someone pointed out in this thread, and that makes him intimidating right from the get-go for small creatures -- not to mention the fierce expression in his eyes when he is getting ready to spear a fish from the water. He's big, too, and when he stretches his long neck all the way, he's really tall. Alfred doesn't terrorize me, fortunately, as I'm always at a fair distance when shooting him (that's what long lenses are for!) or if I or anyone else does get too close for his comfort, he promptly takes off.
