While in Manjung, Perak, the local council of Manjung representative took all of us to visit a few BHs.
The organiser, Mr.L, took us to his BH (not that successful) and two stand alone BHs situated just beside those high voltage cable pylons.
I was accompanied by Mr. George who happened to be a qualified professional electrical engineer. He used to measure these low frequency electronic wave radiation generated by using some specialised gadget and determined how dense they were.
The moment Mr.L indicated that the two BHs failed, Mr.George whispered to me what is wrong when your birdhouse is located below those cables.
According to George, the electrical cables do produce a kind of low density electronic wave radiation that are very sensitive to those birds navigational system.
According to him the radiation normally can disorientate the birds flight pattern. Their navigational capability will be greatly affected when they passes the radiation. Once this happen they will not be able to locate their house or even the entrance hole???
As such he stressed to me that try not to built your BH too closed to these high voltage cable or pylons.
Well I am not an electrical engineer but I hope the advise given by Mr. George is of use to all newbies.
If you need more clearer explanations please contact George directly. His contact number is 012-6096371.
Well I managed to enter one of the two and from what I saw there were more then those electrical radiations.
The BH, I entered, have many things that were not right. The humidity, the internal darkness, the temperature were not right.
The owner have little knowledge about swiftlet farming.
The two i.e. those radiation plus little knowledge might be the core reason why these expensive building are rotting away with no birds.
