His assessment on why his nests numbers were little are as follows:
1) The first year it could be due to the strong cement smell.
He did very little to remove the cement smell
2) The second year he suspected that it was due to playing the pooling sound on his monkey house roof.
He uses three sounds, the internal, the external and the pooling sound.
This was preached by his Sifu after attending his seminar at Holiday Villa.
According to him the pooling sound was playing havoc since those birds gathered above his monkey house areas but refuse to enter his entrance hole.
After having a long though he swabbed the pooling sound as his external sound.
Let see what happened next. I think they now begin to come to the entrance hole and entering the monkey house.
This was when I met him to view his video clip showing how many birds were hovering above his BH.
Well he might have many other problems inside his BH.
I told him that with very limited knowledge about swiftlet farming he might face a very similar issues in getting those birds to built their nests.
The best is to get someone experience to inspect his BH and perhaps inform all the possible things that he can do to improve his chances.
One important issue was how to align his external sound tweeters to pull those wild birds to fly not only into the monkey house but right to the back of his nesting room.
There is no use of getting them into the monkey house but they never fly into his nesting rooms.
Since he just swabbed the pooling sound as his external sound he wanted to observe what happened next.
I fully agree with his to give the house a short period of observation see if the nest number will start to increase.
If they remain the same or very little improvement he should get someone to visit an pinpoint any thing wrong inside.
It was nice to meet someone who claimed to be a very passionate swiftlet farmer.
I look forward to visit his BH in the future.
