Not only the nest did not increase but the contractor went missing (refuse to answer phone calls).
Another case of BH that was taken over by the building contractor from day one.
The owner wanted him to comply with the BH design that was proven but the contractor have his own idea.
I was invited to inspect this BH located somewhere in Sedili, Johore.
The BH was a three stories 30 feet by 80 feet and 10 feet high per floor stand alone located of a very nice piece of agricultural land.
Prior to entering the BH the owner shared a few things that might teach you some lessons.
This BH was put into operation for almost 1 year and 4 months.
One very big mistake that took place was when the building contractor erect the building to his own design.
Remember he is not an expert in swiftlet farming but just a building contractor.
He nullified the owners request to erect a BH to his wish. At the end of the day not a single bird entered the BH.
He stopped answering all phone calls and even if he answered his excuses will be the same "I am not free".
The owner took his own action by shutting down the main entrance hole and open a new one.
With very little idea he chose one of the wall of the building and put up some internal partitions here and there.
The result was not bad. He got his prayers answered: 2 nests.
After that there was no longer any new nest.
"Pak Harry I need your expertise to tell me what is wrong and how to reactivate my BH", his request to me.
I took about 45 minutes to check what went wrong inside and outside.
I listed the followings that you should try to remember not to commit the same mistakes:
a) The BH was line directly East to West.
The owner confirmed this since he wish to minimize direct sunlight onto the larger walls of the building.
He got a strong point on this but he was not informed about the morning light.
b) The LAL was located closer to the east facing wall and very small.
Beside being very small there was a staircase blocking the LAL space.
The small space was not the right thing to do if you which to pull those swiftlet to the lower floors.
The only wise thing to do is to hack the staircase and use the second staircase to climb up.
c) The owner recently shut the monkey house above the LAL and opened, his own initiative, a new entrance hole at the wall on the west about 60 feet away from the LAL.
The chance for the tenant to locate this LAL is very slim.
My recommendation to the owner is to relocate his entrance hole closer to the LAL
d) The new entrance hole, now locate at the west wall, will have a big impact on the morning light into the BH.
Remember those birds needs this morning light to guide them out at dawn time.
If they wanted to be out of this BH they have very little choice but to stay closed to this window.
The chance to go further inside or to other floors will be slim, I told the owner.
This second point is stronger than the previous point.
If we put the two together I strongly recommended to the owner to relocate the entrance hole to the wall facing the east and closer to the LAL.
e) The birds once the entered the BH need to be guided so that they will fly above or into the LAL.
There will be a number of partitions to be erected to guide these new tenants.
I showed to him the precise location where to erect those walls and where the opening will be done.
f) The number of external sound tweeters were little.
Just imagine the current hexagonal tweeter was with only two small tweeters.
My recommendation to him was to install additional power tweeters, new hexagonal, a bazooka and perhaps pole tweeters on the window's perimeter.
g) The current internal sound tweeters were all facing the wrong direction.
Yes they were facing the opposite of the flying path.
Main reason was that the old entrance hole was closer to the east and now moved to the west.
The owner did not re position all his tweeters.
h) The number of internal sound tweeters were a bit on the low side.
i) There was not a single external sound tweeters inside the nesting rooms.
The nearest was at the LAL areas.
j) You can guess what sounds were used as internal and external.
Based on the above I would say that his BH if it remain as it was, it will be officially be classified and a dead BH.
Nothing to look forward to and hopefully he will read my 15 pages visit report.
I really wish those who wanted to build their first BH to come and visit this BH and see the kind of mistakes that should have not happened.
Please please please, if you have very little knowledge and your contractor is just a building contractor don't try to erect a BH.
Call Harry if you wish to safe guard your investment.
