Important of Bird Colony

If someone asked me what is the best internal sound? My answer would be the "LIVE" natural sound from the Colony Birds, not playing from the tweeters.

If someone asked me what is the common thing for those successful BH? My answer would be there are a lot of Birds Colony.

We play internal sound to let new birds know that there are a lot of birds in the BH. We know this method work as birds like to make their nest at the tweeters. Imaging there are > 20 birds at the same area singing and playing LIVE. Do you think the effect would be better than those tweeters?

So my next focus would be "How to form as many Colony Birds as possible". Either by using VIP room, more tweeters, special aroma.......

Another Upgrade - New Partitions.

My BH nest counts has been increasing steadily for the last few months between 2 to 19 nests every month. But, I think I can do better and I want more. That is why last week I added 2 new things in my BH.

1. Ultrasonic Humidifier which I already mentioned in my early blog. I hope with this humidifier, I can make my BH temperature and humidifier less fluctuate.

2. 3 more partitions such that the BH is darker and the humidity in the BH is more stable.

The next upgrade in my mind is to install Bullet Tweeter at the 2 side of the partitions. With all the good feedback I received about the tweeter, it should help to increase my nest count to 2 digits every month.

My DIY Ultrasonic Humidifier

Finally my DIY Humidifier is in operation now.

Just to share with you all how I DIY my humidifier. Of course first you need to buy good and reliable mist makers. So, I bought mist makers from my friends after he test run no problem > 8 months for more than 10 units. Well, made in China stuff, you have to do so.

A hole is cut for PC Fan.

4" hole is cut for PVC. Initially I cut the hole at the center of the container which is wrong (picture below is wrong position). You should cut the hole at the opposite end of the PC Fan. The mist will able to flow out smoothly from this opening. Another small hole is cut for water inlet.

The water level sensor

I used 2 cable ties to tie the PC Fan instead of 4. By doing so, I can insert my mist maker through this hole. In future, if you want to do maintenance work, you can remove easily. No screw no cutting.

I used filtered water for my mist maker. The mist produces will be clean and less contamination or maintenance require.

The DIY mist makers is ready to run. I used wire mesh to cover the 2 PVC output to prevent birds flying when not in operation.

The mist makers is connected to humidity controller. The immediate result I observed was the BH humidity reach to set point in very short time. The mist is very fine, light and can travel very far as compare to Taiwan humidifier. I only need to use 1 for 20x70 shop lot. The best is........almost NO SOUND :)

I will update the temp and humidity chart 1 month after use. If you interested to buy, RM850 for 1 set include 10 heads mist maker, float sensor, PC fan and delivery in West M'sia.

Bullet Bazooka Water Proof Idea By User

Thanks Eugene for sharing how he DIY his Bullet Bazooka.

Hi Victor,

That's how I improve water resistance of the bazooka.

Use a thin saw and saw less than half cm drain at the bottom. 4 layers of wire net use for mosquito netting and clip at the mouth to reduce direct water penetration. When put it at 30% angle, spray with shower most water will drain off at the net, some water still penetrate and drain at bottom. Even a non waterproof cloth is ok as water will drain at bottom of horn before tweeter. When screw in tweeter leave a small gap btw tweeter and horn so water will get stuck and drained off.

I intend to put below a external roof so full resistance is not really a concern.

Tweeter Testing - Ext1

I have recorded different bird sounds played back using different tweeters. From the sound, you can't hear the different. But the Frequency response graph can tell the different. Below are the test results for Ext1:-

Meet Vietnam Friend

Last week, my Vietnam friend come to Singapore to meet me. We chatted for almost 2 hours and we exchanged information.

He has a small BH in Vietnam on top of his house. Not big but the result is impressive. He DIY himself and after 8 months in operation, the nests counts reach 80 now. He has his own way to attract birds which are very different from what common practice now a day.

- He only use 10 internal tweeters in his BH. But those tweeters are good one. His reason is, he don't want to make the birds confuse
- He play the same internal and external sounds.
- He edit his own sound.
- He has his own way to control the internal temperature. Fyi, the temperature outside his BH can vary from 10degC to 37degC.

Below are some of the pictures he share with me in Vietnam (not his BH). The top one not so good. The bottom one harvest 20kg/month.
