During my visit yesterday at this revamped BH the owner claimed that the bird's favorite choice seems to be the middle floor.
Their main target was the VIP room.
It used to be the top and the lowest floor but now they move to the middle floor.
The modifications carried out in this BH must have caused the change of location.
The erection of partition to guide those birds to fly above the LAL and the positioning of external sound tweeters must have directed them to the 2nd floor.
I can see the increase of fresh bird shit spots inside the VIP room especially along the last, second last and the third rows.
This floor used to be with the least number of birds.
One very positive observation was that the number of birds playing above the main entrance hole were very encouraging.
It used to be very quite with no birds above the roof top but now it seems to be busy all the time.
Main reason being the effectiveness of those external sound tweeters.
The owner install more external sound tweeters around the main entrance hole plus the roof.
If I was not mistaken the owner installed at least one hexagonal tweeters, 4 mini bazookas, 8 power tweeters and 8 3"x 8" coiled tweeters.
Prior to this the hexagonal tweeters fell down and only 4 small tweeters around the main entrance window frame.
The owner went berserk with 5 amplifiers for external sounds alone.
He wired one dedicated to the hexagonal tweeter.
One for the bazooka and those power tweeters.
One for the external sound tweeters at the top entrance hole areas and the LAL.
One for the external sound tweeters at the main window and along the staircases.
One more for the external sound tweeters for those located inside the nesting rooms and VIP rooms.
He must have read a blog that tells him about how important external sounds are.
I am sure it came from one of my posting.
Another unusual installation inside the nesting rooms was the number of fake nests installed.
I sense that the number of fake nests installed was somewhere around 500 or perhaps more per floor.
I noticed that he put extra effort in cutting those fake nests properly curved to suit the shape of the corner covers.
If he did nothing the fake nest will break when installed.
This is more than what I expected.
Anyway I complimented his effort but told him to remove these fake nests once they were used twice by those couples.
Once the nests number touches 1000 nests please try to remove them.
These fake nests main objective is to help those young couples but once they are experience enough they don't need these fake nests anymore.
One thing for sure was the effectiveness of those VIP rooms.
Those birds, as per my description, prefer to stay deep inside the VIP rooms.
I was right and the BH owner also realized that.
I told him to continue making sure that his BH runs well and try not to disrupt the sound.
His BH needs an auto starter. This will ensure that during thunderstorm the auto starter will reactivate the power supply if those lightning strike close to the BH.
My best recommendation is to go for Hager or ABB model.
I spend a number of hours to choose the right external sounds for the BH.
The best was SELKING and Super 208.
"Please make sure you safe these two sounds in your computer. If you don't I guarantee you that you will regret." I pressed on him.
I wanted him to keep these precious sounds properly.
In case of any mishaps he can quickly recopy the sound.
Good example is well your thumb drive malfunction or someone entered his BH and steel the thumb drives.
Keep them properly and make them as your sound library.
I was promised a good lunch and happy to sit down with his family.
