How To Keep Blue Heron From Eating Pond Fish?

Herons are beautiful, long-legged with long neck freshwater and coastal birds. They may be elegant looking and intelligent but they always look at your fish as a dessert.

Because they are intelligent birds, you will have to be resourceful and creative to keep them away from luring your fish.

Herons are rampant in North America and would migrate in the upper Midwest America and Canada over the summer, and winter over the winter season. Their body structure is strategized in an S-Shape when they dive into their prey.

They are carnivores and most of them feed on live aquatic animals, like fish, crustaceans, and mollusks. Their usual hunting strategy is sitting motionless in shallow waters and wait until the prey comes to them.

They may be in either in an upright position or a crouch position. If they’ve seen their prey, they calculate the distance and position of the prey, and that’s where they start to spear their prey.

How To Protect Your Fish

Herons may be ninjas in disguise because you might never know when they are going to attack their prey, especially in the larger pond. So, the question is: how would you be able to stray them away from your fish and discourage them from making your fish as their meal.

Herons are territorial birds and they usually claimed the pond for themselves. If they’ve seen another heron guarding the pond, they would step back and look for another pond.

However, don’t use decoys during April and May because they may be looking for potential partners in this mating season.
