WW we are all very discouraged by what has been happening to our rice bowl but we are doing our best to reverse the current trend. Let us hope for if we do not have any hope it will be the end for all of us.
For a few hundred years, EBN has been in great demand and because of the action of a greedy few, consumers have lost confidence but I hope eventually this confidence will return as we learn to control the cheaters, adulterers and the profiteers.
We, to protect our industry must make a concerted effort to stop anyone from adulterating natural EBN. Even if it means reporting the persons to the authorities. We cannot risk another incident. There will always be cheaters but if we show them that we mean business, there will be fewer. I know most of us had been guilty
of turning a blind eye on those making 'Blood' nests and false or adulterated nests for the past years. We got to change.

I have to agree some pros can even produce lemons. Earlier this year, i posted some photos on my newly extended bird house. 10 months later as today, not even a single bird nest in the new BH. Old and new BH just side to side, i connect them internally and use the same sounds. Still no result. Going to make some modification during semester break.
Throughout my observation in recent years, i notice swiftlet does change their behavior. Previously it was quite easy to lure the birds into my bird house. But now, it is so difficult even i fail to lure my own bird in the past 10 months.
Yes, observation is the most important aspect in improving your BH.
It is quite well known that joining a new BH to an existing BH by taking down a wall etc. will usually not work.This is because the birds in the old BH have already got the map of the old BH into their heads and the new annexe does not 'exist'. The simplest solution is to have separate in/out holes for each BH. You can keep the knocked down wall but have another dog kennel or well and the birds will think it's a new place. The advantage is that young birds from one house will populate the adjoining house not knowing that it's the same. That has been basic knowledge for sometime now.
For unknown reasons AF are attracted to the calls of the same specie but will not always react in the same way. A good call here might be a bad call elsewhere.They always react when there are changes to the call patterns which is why many people are making constant changes to their calls and also editing new sounds. All these are basically just the same sounds recorded from the birds when they roost. Just mixed and edited over and over again to make it seem different. We need to understand the birds' language but failing that, mixing and editing seems to work wonders.
For any machine to work flawlessly for a long time it has to be simple and strong. The chicken coop humidifier is proven and tested over many many years, simple and built of materials that should last for several years. OTOH the ultrasonic humidifier, in principle is very simple but prone to fast wearing. The crystal surfaces have a fine conductor layer which is corroded by water. The conductor is often made of cheap copper which through electrolysis will not last long. The crystal being quartz glass will fracture when over stressed or the conductor will delaminate. The frequency the crystal is made to vibrate is very high, 20,000 cycles per second or more and made to work in a dense medium like water which in turn causes more stress similarly our tweeters last much longer because it works in the air. Think of the chicken coop humidifier at 1000 rpm or 17 cycles per second and the ultrasonic at over 20000 cycles per second, which will wear out first !
Luck is expertise that others do not understand. Careful and keen observation will go a long long way in eliminating 'Luck'
