We transformed to something like this.
It looks like as if the BH went to the barber to have a hair cut.
My main reason was to reduce the roof extension to something that will reduce unnecessary blockages of the birds flying down from the hexagonal tweeter areas.
We also installed about five power tweeters on the wall of the monkey house plus change the hexagonal tweeter.
It used to be those giant type with four mini bazooka tweeters covering only four directions.
The new hexagonal is with five tweeters.
The perimeter wall area was painted with a special black paint with a kind of bird smell.
It help to make the entrance hole looks larger.
If you look carefully the window now is layered with nesting planks.
The wood will help our installation of tweeters on it.
Have a look at some pictures taken during the roof cutting operation.
It was a tight operation. Yes the only hole available to sneak onto the roof is thru this small area found by by workers.
My boys did a very good job and they eventually complied to by design requirements.
