I whatsupp the above picture to the Sedili BH owner.
"Brother look what I have found on the ground floor of your Sedili BH?"
The picture shows a sizable bird shit spots on the ground floor made by at least 5-10 birds that entered the night before.
This proved that they have no problem to fly to the lowest flow after the LAL areas were modified.
Prior to my intervention those birds were unable to find their way down.
The lowest floor will be the most difficult for them to fly to.
This phenomena is mainly due to a few good reasons.
First is the flying path that they need to take from the top most floor, actually the roof top, to the lowest floor.
If you make the path difficult to fly down those birds will not be impressed with the twists and turns.
I normally classify these wild birds as a lazy lots.
If you make it difficult for them to fly down to the nesting rooms they will usually will not make the attempt to locate those rooms.
Second more important observation is that if you allow them to fly freely to the top floor these birds will take an easy way out.
They will only stay to the top most floor.
So you need to curb them or make it more difficult to fly to the top most floor.
For this Sedili BH I erected a box to prevent them from entering the top most floor from the monkey house entrance hole.
The only way for them to populate the top most floor is to enter from the second entrance hole located at the back wall of the BH.
The third is the morning light.
If you have no window facing the east or the morning sun direction those birds will also refuse to stay any place that is too far from the main entrance door or windows.
This is what is happening in most BHs that I have visited.
The owner is not aware about the importance of having the morning light coming into their BH to guide those birds out of their nesting rooms.
If you can plan your BH to have a window facing the east.
For this particular Sedili BH I opened a special hole just for the morning light purposes.
The hole was 3 feet by 1.5 feet and with no external sound tweeter around it.
Its main purpose is to allow the morning light to enter the BH.
The fourth and most important is how you use those external sound to pull them down.
Remember when they enter your new BH it is not because of you new BH but those attractive external sound.
If you know how and where to place those external sound tweeters correctly they will be pull down to those spots where you want them to be.
I focus more on the staircase and the LAL areas.
I know where to put those tweeters and how to control the sound volumes.
The final result is "HOLA" they came down during my test run during the last few days when I was about to hand over the BH.
It is good and proof a point.
If you know about what they likes or dislikes or their weakneses you should be able to push them to stay on the specific locations inside your BH.
