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.
Vietnam - a new White Gold Mine.
