Which means all Bhs should be different in terms of design and should adapt to the environment where the Bh is to be built.
In East Malaysia (Sabah and Sarawak), there are huge existence of Seriti when the Bh entrance hole is too large, light could easily penetrate into the swiftlet farm and the nesting areas would be too bright. This would attract Seriti to stay and build nests in it. Whereas in Peninsular Malaysia, Seriti is rare species, therefore a big opening entrance hole won’t attract Seriti but it would attract predators such as Owls. So deciding on the size of the entrances, one needs a clear understanding of the pro and cons.
So what is the best size for the entrance hole? 1x1, 1x2, 2x2, 3x4, 4x4, 4x7, 7x7, etc. You will not get the answer until you could visualize it, which is not an easy thing to do.
The Entrance hole is an in and an out route, often at times many prefer it to be big cited, easy for Birds to fly in and out. To a certain extend it is true but a big entrance also has its disadvantage such as thieves, predators, light density control and etc.
Before deciding on the size of the entrance, it is important look at the how you want the internal (partitioning) to be. Both the internal partitioning and the external hole size are interrelated. This applies to all Bhs. Big entrance hole require more partitioning to reduce light. Small entrance hole requires fewer partitions, but it is harder for birds to maneuver. In order to decide on this we must weigh the importance of each decided size. That would subject to your creative ability and strong basic knowledge in swiftlet farming.
When I say basic knowledge, that does not mean things that you had learned from attending seminars which are mushrooming everywhere. We are not talking about how swiftlet farming started in Malaysia, its history or about the size of the Bh, or about how to put fake nest, or even about creating special rooms for birds.
We are talking about creating a good and big Runway, a good boarding area, a good transit sections’ and so on. By doing so, all those planes be it 737, 757, A300, F-16, Sukoi, or Hornet could land without any obstacles or difficulties.
To be a successful swiflet farmer, you need to know all these. Imagine what if you have spent millions of dollar on a new Airport and later, to discover that it is too small or the facilities are not sufficient enough to support all the planes that are coming in? (Malaysia Boleh).
Then all flights (planes) will choose to land in Singapore, Indonesia, Thailand and so on instead of the Airport that you had built. If your swiftlet farm is similar to that of
Do not copy the same design from other Bh. It may work in a particular area but not other areas. What if you had copied the “Malaysia Boleh Airport design”...ha.ha…? This is not a joke. I have seen many swiftlet farms sharing a similar design over and over again, most are likely to fail.
