The Best Way To Prevent Those Barn Owls From Entering Your BH !!!

I was having some discussion with Mr Goh of Sepang.

He drove to KL to meet me for those "Black Cloud" birdcall sound. Beside the BC he wanted nearly all my best collection.

While downloading those sounds he described about how many BHs he has (some are on JV). He admitted that currently has 7 BHs. A few in Selangor and some in Melaka.

One of the event that happened to his BH was the attact from barn owl. The BH that was attacked used to have 300 nests. When detected, less then half were gone. Most ran away while others became the food of the owl.

It seem that the barn owl started to built her nest in the BH.

I asked him, what have he done to prevent the same from happening?

"Well Harry I have install those electric wires around the entrance hole. The electric wires are similar to those electric fence system where those electric wires are connected to an energizer. The energizer will deliver a high voltage electrical pulse every 2 seconds or so. Once those predators touches the wire, either stepping on them or touches them, the will be jolted from the pulse."

"The system not only will scares the predators but it they continue to cross over, like snakes, they will be dead."

"I have seen many dead predators on my roof top. There were snakes, house lizards, wild lizards and so on. I think it works."

"For Barn Owl, since they need to perch at the area surrounding the entrance hole, they will accidental land on the wires. With the jolt they will not try their luck. The system is very suitable for the open roof entrance type."

"The cost of the system was about rm700. You need to add some installation cost."

From wikipedia:

Electric fences are designed to create an electrical circuit when touched by a person or animal. A component called a power energizer converts power into a brief high voltage pulse.

One terminal of the power energizer releases a high-voltage[clarification needed] electrical pulse along a connected bare wire about once per second. Another terminal is connected to a metal rod implanted in the earth, called a ground or earth rod.

A person or animal touching the wire and the earth simultaneously will complete an electrical circuit and will conduct the pulse, causing a painful electric shock.

The effects of the electrical shock depend upon the voltage, the electrical current used, and the degree of contact between the animal and the fence or ground; it can range from barely noticeable to uncomfortable, painful or even lethal.
