BH Updates

Due to busying with project work, only able to visit to my BH yesterday. Not much progress and only added one new brid nest mark. It look like the :Aroma" I am testing now not effective to attract any swiftlet in my area to help to increase the bird nest in my BH.

Some changes applied to my BH.
1. Using 2 different internal sound for different section of the BH by edited the internal sound. This is to test out the effectiveness of the internal sounds.
2. Changed the external sound

I also noticed 2 more new BH started operating near my BH area, just few shop house away, good sign is the area not bad but this increase the competition. It is more difficult for my BH as the growth is too slow..
