This might be the last job for 2013 for me and my crew.
The Chenderong Balai BH is a three stories stand alone building about 20 feet by 70 feet by 9 feet high per floor.
The two floors, top and middle, were completed as a BH while the ground floor was used as a house.
It was mentioned that this BH was put into operation about two years with only two visible nests.
The two nests were abandoned due to some reasons and I was asked to look into bringing them back.
I mobilized my crew to site on September 18th 2013 and make a number of observations.
The BH was on a piece of land close to some padi fields and palm oil trees.
The walls of the BH was single layered however the roof was installed with those asbestos roofing sheet about 3 -4 feet above the top most ceiling.
The BH internal temperature seems to hit about 31.8*C and I think some kind of heat shield will help to bring down the temperature to below 29*C.
If you looked at the asbestos roof, the extension, was lesser than 1.5 feet long. It would be better if the extension was 3-4 feet. The shadow will help to reduce direct sunlight onto the walls.
The next unusual observation was the number of ventilation holes on the main walls. It was only one per beam length on the main while at the breath it was about 8.
The BH was initially designed with one entrance method i.e. via top entrance but was recently introduced with one new side entrance hole.
The most strange and unusual was the reaction of those swiftlet to all my external sounds played.
They seems to have some unexplained reasons for not reacting to all those "effective" sounds.
The only sounds that they showed some attraction were those oldies that I rarely used any more.
The number of them reacted was still below my expectation.
This might be due to several reasons.
The first is due to not the mating season. Usually when they wanted to mate and get paired they will react more positive to your BH external sounds.
Second might be this particular BH must have been black listed by these flock of birds. There are many reasons why they black list this BH but one most important might be the high temperature inside.
The third have something to do with the number of swiftlet that were observed flying on the roof top. There were a couple of times that the "swiftlet' turned up to be the white spotted swift that flew closed to the roof. These whited spotted swift give no reaction to external sounds.
The number of birds that flew above this BH was about 200-250, which was a bit too little to a normal standard.
Whatever says and done my crew and me will be busy with our plans.
The first thing which we have started were the followings:
1) Installation of additional external sound tweeters at the entrance areas.
2) Heat shielding of both floors.
You are always welcome to site and visit us.
Call 017 7551318 if you wish to come and view the BH during our revamp operation.
Bring some mineral water if you happen to pass by.
