The Problem With Herons

Herons are large fish eating birds about 3 feet tall with long legs for wading and a long neck. The body is about the size of a chicken and they nest and lay eggs like most birds in spring. Their nesting sites are communal and are called heronries. In medieval times they used to be hunted, roasted and served as a delicacy at banquets held by the local lords and ladies. This is a practice that many pond keepers would like to see revived, but since herons became a protected species some years ago their numbers have soared. Many sanctuaries have been made for them each with its own body of water and heronry. It is true that they nest in them and fish locally for food, but it is also true to say that their desire for more fish often takes them many miles away from the heronry to well stocked fish farms, reservoirs and to private pools including of course many back garden fish ponds. All those bright, colorful goldfish and Koi make easy pickings for a hungry heron in the middle of winter when the fish in the rivers and canals are at the bottom.

Herons are said to walk into the water from the edge, so a 12 inch high wire strung around the perimeter of the pond, very close to the edge, may help to deter them. However this sometimes fails as herons have been seen landing in the middle of a 3 foot deep pond and diving for fish before flying away. Herons will keep coming back once they have found the pond until they are sure it is empty. Even if they canít swallow the fish, and they have a prodigious appetite, they will spear the fish and leave it to die. Wires strung across the pool zig-zag fashion should deter them and are a lot less unsightly than a strong net.

Another method is a trip wire with a small explosive device attached that can be bought from some aquatic retailers. Artificial herons placed at the side of the pool are said to deter them from landing, but we have all heard the classic story of a real heron trying to mate with a plastic one. 

The modern alternative to a trip wire is a battery operated motion detector. These can be connected up to all sorts of things such as a water sprinkler and will prove a very effective, but harmless deterrent, against Herons and many other pests including Cats!

If you want to provide more discreet protection against Herons then a floating plastic mesh system is now available online. The pack comes as a number of either, smaller discs, or larger, squares that can be simply connected up together to form a floating grid across your pond. Each piece is just over a foot across with the mesh large enough for plants to grow through, but not for predators to go fishing. The system does seem expensive for what it is, but it does provide good shelter for fish without detracting from the pond.
