These BHs seems to be facing some kind of nest population growth problems.
One common similarity of all the three were the use of the same consultant who copied a number of my ideas but went too much with his wild ideas.
It started a number of about three years ago when a so call consultant hailed from Perlis with some title "Doctor" in front of his name.
His skill in convincing people to follow his method is superb.
Nearly 12 locals were dragged into swiftlet farming using his untested ideas.
All the 12 BHs in this small town were closed to empty for a number of years.
I was discovered by one of the group leader and asked to help in reactivating them.
This was what I asked the leader to do.
During my lunch break with him I forward my request on the first thing he should do.
"Can you delete all those teaching from Dr?"
He agreed with this simple idea.
"If you want me to help you with all these failed BHs you need to follow my method."
Let me describe to you what are those strange things found inside the 3 BHs visited.
1) Hanging Aroma Bottles:
The three BHs were with this hanging perfume bottles. Lots of them and I think they block birds from flying closed to the nesting planks.
The perfume was nothing more than those raw nests added with Pandan leaves smell.
Some of these bottles were wet with the aroma and they become sticky.
What happen after this is that they will actually capture those birds.
One bird was trapped onto the sticky bottle.

2) Fake nests made of Clay.
The consultant seems to be obsessed with the deployment of fake nests.
He uses this fake nests made of clay.
Nearly every internal sound tweeter there will be a fake nest on the top and one perfume bottle hung at the bottom.
One very strange thing that I suspect the clay fake nest was the culprit was the number of young bird carcasses on the floor.
One of the three inspected BHs have this strange baby birds drop onto the floor.
There were more than 15-20 carcasses and a few were still alive.
I was asked on the possible reasons why they slipped and fell onto the floor.
My pass experience tells me that they will drop down due to two reasons:
a) When they were running away from predators. Usually those Geckos.
b) When their parent did not bring food home for at least three days. They will be so hungry that causes them to release their grip onto those netting of the nest and crawl out of their nest.
The two reasons were not applicable in this BH. The weather was okay and food were abundant. There was no gecko found in the BH.
This was when I begin to suspect the clay fake nest.
I took one of the fake nest that were with tenant using it.
It seems that those swiftlet did very little work in creating those netting for their baby to grab on them.
With no netting when those babies wanted to poo they slip down onto the ground.
My suggestion to the owner was to remove all these fake nests.
That might stop the death of young birds.

(This was the fake nest that were slippery. Look at the amount of saliva that were used.)
3) Too many internal sound tweeters and fake nests.
The number of internal sound tweeters and those fake nests were just too many.
The owner were forced to use more than 4 units of internal sound playing amplifiers.
The tweeters were not well located and those fake nests were making the tenants lazy to produce their saliva.
One of the BH was with not a single nest but all its tenants were using those fake nests.
My description to the BH owner was "They stay but refuse to pay their rental fee?"
On the part of the BH owner they don't actually understand the basic function of those fake nests and how to remove them once being occupied.
