The same BH was pronounced dead my its owner (about four months ago).
I am impressed with it myself.
Beside opening a new entrance hole the following were done:
1) Install a hexagonal tweeter above the new entrance hole.
2) The new entrance hole was actually there but shut down due to some unknown reasons. I opened it and in fact increase its size.
3) I also installed about 8 power tweeters around the monkey house.
4) Somewhere at the roof area I also installed a mini bazooka facing the neighbor's BH.
5) The two entrance holes were equipt with a number of AG 35 external sound tweeters. Each hole is with 8 pieces of it.
6) The zinc roof were cut to minimize any problems during tweeters installation.
7) The permanent steel gate at the main entrance hole was totally dismantled.
8) The monkey house internal walls were painted black to minimized those bright light.
9) The walls were also installed with a number of AG 35 tweeters to pull those birds into the connecting door.
10) The connecting door was reduced in its size to reduce the light into the nesting room.
11) The door frame was installed with 8 tweeters.
12) A room was erected just after the door.
13) The VIP room at 2nd floor was properly decorated with all those frills that will attract these wild birds. The moment they entered they will refuse to leave.
14) Two humidifiers were installed inside the VIP room.
15) The VIP room was applied with mutiara aroma.
I am very sure within the next few weeks we can see lots of bird shit spots on the floor.
This time I wanted them to stay inside the chosen VIP room and not all over the place.
