Still no Sign of Bird

Check the bird house recently. There is still no sign of bird staying in the bird house.

Using the temperature data logger, I noticed that the internal condition is very good. The temperature is below 30 deg C and the humidity is 85%. All the micro conditions in the bird house are good.

So the only problem now is the sound. How to advertise to the birds to inform them that there is a good bird house for them to build their nest and lay their eggs. I have changed a few external sound already but the result was not good.

When I was standing in front of my bird house, I noticed that external sounds were coming from all directions. I can hear external sound coming from the opposite houses. I realized that the sounds from the opposite houses are echos from my external hexagon tweeter. Since most of the houses around my bird house are empty, they can create a lot of echos.

I have decided to shut down the hexagon tweeter and install two bazooka tweeters facing directly to one of the bird house nearby with a lot of birds. Hopefully, I might attract some of the birds from the bird house. ;)

I have also changed a new sound. Let see what is the result in a few weeks time.
