Have you ever try to use those bazooka tweeters ?
They can be useful if you know how to effectively use them.
What can be the special reasons why you should try to install one or two on your roof top areas?
My answers can be something like these:
1) You wanted them to fly down from on their way home.
2) You wanted your neighbor's young birds to take notice of your BH.
3) Your BH is simply situated in an open area and you wanted your external sound to cover more areas.
For Tanjung Karang (TK) BH, I urged the owner to consider installing two bazookas to attack point number one and two.
One very strong point about TK BH is that its location.
I came to the conclusion that it is situated below the birds flying path when they are returning home.
The only weakness is the number of them flying right above it.
My estimate is around 500 or so.
There is a very strong chance that another 500 flew way up above and are not able to detect the current external sound used.
The best way to improve the number is to use a long range bazooka tweeter and shot the most probably location where they can hear the external sound.
For this TK BH the direction is at the North 30* East.
The second reason have something to do with the neighbor's BH.
I was told that two of the four BHs located about 100-400 meters do have a sizable population.
My idea is to use one of the medium range bazooka to lure those young birds from the neighbor's BH.
I need to check which of the four BHs are doing well (with a lot of birds entering the BH in the evening).
Once that is done I will zoom the medium range bazooka towards the rooftop.
The whole idea is to lure those young baby birds that took their first flight out of the BH.
These young birds are considered to be very easily lured since they are always wanted to explore new things around their areas.
If for some reason the birthplace is not well looked after, for example too dry, they will find a good reason to move to a better home.
Let us hope that the BH selected is in a deplorable condition and it owner do very little to make sure that the internal environment are wet, cool and dark.
If these young birds wanted to find a better house its going to be this revamped BH just nearby.
Will take some photos to show you all on how the two bazooka tweeters are installed.
