It depends on what kind of heron. I'll tell you what I know about the Great Blue Heron. Some migrate, some don't. I don't know what the Great Blue Herons in Europe do, but the general rule in North America is those east of the Rockies and north, winter in Central America and the northern part of South America. Those in the southern states and southward along with the Pacific Coast are year generally year round residents. It depends on food supply. A Great Blue Heron will eventually discover your Koi and eat every last one. They are beautiful birds and fun to watch. Anyone who has expensive fish outdoors would be foolish to not take precautions. It's a felony in many states to shoot them (as with all migratory bird whether they migrate or not) and in some cases jail time. I know many people who stocked the former koi pond with 10 cent feeder fish to lure a heron so they could watch it fish.
Great blue herons are grayish blue and have a thick dark caplike marking on their heads while white herons are completely white.
