“James No birds fly into my Bh. They just circle above my Hexagonal Tweeter and all of them fly into my neighbor’s Bh. What should I do?” cried Mr.L from Johor.
His Swiftlet farm was a 2 storey shop lot built next to a very successful Bh. Every time when he switches on the Hex sound many birds come and play but all went into his neighbor’s farm. This situation worried Mr.L.
He told me there is nothing wrong with his Bh and all seemed to be perfect but he can’t figure it out why birds are reluctant to go near his entrance hole.
I told him I can’t say much until I see the Bh myself. There are many things in the Bh that many Bh’s owner may not noticed. It needs experience and skills to figure out what actually went wrong.
His Bh is an Open Roof (OR) type and his neighbor’s Bh is a Dog Kennel (DK) type. It is obvious that his neighbor’s farm has the height advantage. But height is not the only key factor that attracted all birds into its Bh. There are other things too.
In this case after looking at his Bh. It is obvious that Mr. L had made mistakes without noticing it.
The position of the Tweeters shouldn't be at the top which I had mentioned before in my previous article. For this door entrance type the tweeters should be placed at both sides (left and right). 2-3 feet from the top. Depends on the height of the door.
Having tweeters on the top of the door is not advisable. That is why Mr.L complained no birds wanting to fly near the Bh's entrance hole. Secondly the 90dg 2nd entrance to right to the nesting area is not impressive. I won't favor such design.
