He complied without any fuss.
I listed a few advantages and I think he will have a better chance to get more birds inside if he does so.
While I was finishing his first BH located at Lukut he started working on the Merdeka Jaya monkey house construction.
I sketched a picture with how many holes there should be and where they should be located.
I also told him to use those clad zinc roof with 1.5" thick foam to keep the monkey house area cool.
He complied and immediately after doing his work he got be move my equipment and staff to Melaka.
Upon reaching the BH I took a short look at the jack roof (another name for monkey house) and told him they look good but with a few short comings.
The roof was not right since when it rain the rain water will form a kind of curtain which will block his tenants from entering.
Imagine it there is a heavy rain at 7:15 pm and those birds are rushing home to roost.
I don't think they will be able to pass the water curtains. He will look into installing a kind of water drain around the entrance areas, he said.
The next thing that I was not happy about was the so call water pond that he put just below the monkey house area.
The pool was with about 2 inches deep of rain water and there were a lot of mosquitoes.
Could not find the drainage pipe and took half a day to dry it up an cleaned the debris found inside the pond.
Used almost a canister of insect repellent to kill all those mosquitoes.
Once cleaned and dried then I need to attend to how to get those external sound tweeters installed.
The biggest task was how to screw those tweeters onto solid steels.
The was no soft surface around the entrance areas plus its roof areas to get those tweeters up.
This was where our long time experiences came into play.
With a number of wood found around the BH we push our luck through and all those external sound tweeters into place.
The hexagonal was my main gadget to be above the main entrance door.
I have one mini bazooka just at the side facing the birds flying home path.
I also installed a number of power tweeters that are using the same line with the mini bazooka.
The two windows were installed with AG tweeters.
Perfectly executed and completed in less then a day.
After a hard day's work tested and see how those birds responded to the new entrance system.
Yes they love the new thing and every bird that passed closed to it will stop or enter the entrance hole.
