This Tweeter arrangement plan was from one of my readers from the North (see below picture). He had wanted to install the internal tweeters, but he was unsure and decided to ask for a second opinion. He wants to know whether the plan is feasible.
He has come to learn (from some so call experts) that all tweeters should face one side. Well, I don’t agree with that unless all the birds only flies in without flying out and fly in from one direction. Only then, he might be right.
When birds fly into swiftlet farms, they don’t flutter to the tweeters or to the nesting planks immediately. They would circle inside the roving, then the nesting areas and so on adapting themselves to the environment. This process may repeat many times until they sensed a safe environment and in turn, they will hang to the tweeters or planks and stay.
Not all swiftlet birds come from the same colony and some of these birds might fly in circling in an anti-clockwise direction or the opposite. If the swiftlet farms only have tweeters facing in one direction, then it would only be able to attract swiftlet colonies that fly in that one direction meaning, you are deflating the maximum potential of your swiftlet farms.
Yes, it is true that tweeters must face the entrance hole or the route that the birds fly in, but bear in mind that not all internal tweeter should follow.
If you visit a successful swiftlet farm during the night, you will discover that not all the chirping sounds from the residents are from one direction but all directions.
Common sense tells us that if we want to imitate a successful internal environment of a swiftlet farm, we have to follow nature’s intends.
In this case the tweeter arrangement is incorrect. I hope he knows what to do after this.
Good Swiftlet farming All!.
