How come there are more nests on the top floor as compared to the lower floor?
This question was posted to me by this BH owner who own a unit at Carey Island.
During my initial meeting with him I described to him a list of characteristics of a well designed and a good BH.
"Dato a good BH is when the lowest floor is with the most number of nests as compared to the top floors. For example if you have 200 nests in total inside your BH 100 plus should be on the lowest floor and the balance will be distributed on the upper floors." I told him.
If your nests distribution is on the reversed, i.e the top floor have the most while the second got some and the ground floor is the least, you are in a big problem.
Yes there is something not right about your BH.
It could be due to the internal design and perhaps your BH entrance hole direction is wrong.
Remember if your internal design is screwed up example your "Lubang Antara Lantai" is in a zig-zag orientation or you open the LAL at the far end of your floors those birds will not be able to find their way down.
The best design is to have a 45* slanting path where the LAL is properly located which allows the birds to fly down without taking any stoppages along the way.
The next will be the orientation of the entrance hole.
I have seen many BHs where their entrance hole faces the West.
Due to the morning light they prefer to stay around the main entrance hole or only on the top most floor.
Another very obvious reason why those birds are now occupying the lower floors have something to do with the external sound tweeters placement.
The Carey Island BH have this poorly placed external sound tweeters.
To be frank there was only one external sound tweeter inside the BH that was also one tweeter at the LAL beam.
All external sound tweeters were only found at the main entrance areas.
No external sound tweeters were installed inside the nesting rooms and the doors into the nesting rooms.
A very common mistakes which most so called consultants will make.
"Dato, if you want more birds to be on the lower floor try this idea. You install those external sound tweeters as per my recommendations and link them to the data room using at least two cables. One linking to all those tweeters on the upper floor and the second to the lower floor. Try to adjust the external sound played on the lower floor much louder on the lower floor and see what happen within 3 months. Make sure you count how many nest there were on each floor before and after."
He agreed with me and I hope he will take my challenge so that he can prove that I am wrong.
I don't think he can wind this challenge.
Trust me ......
