选择燕屋洞口位置的重要性 Importance of locating the entrance hole

于巴生一间属于我朋友的同学的燕屋，四层高，位于位于巴生养燕热区。燕主是在参考了几本养燕书后自己设计他的燕屋，他在三年前开始启动他的燕屋，一年后还没有看到第一个窝，他就找了一个当地有名的顾问，那个顾问帮他安装二十个假燕窝，然后收了他五千元。又经过一年也没有任何进展，他就完全放弃了，因为他已经尝尽了一切他可以做的，他把声音关掉让它搁置在那里。直到他几个月前他和我的朋友见面提起，然后我的朋友邀请我去看看他燕屋的问题。

我一踏进他的燕屋第一件事我就去漫游室看看，墙壁只有很少鸟粪痕迹，这意味着燕子不爱进来，我能看到他的洞口对面建筑物的墙壁，我立即找到了问题的所在。他的后墙的洞口，但后墙隔一条狭窄的小巷有一排也是四层的建筑屋，洞口的飞行路径受阻。我问他为什么选择了在那里做入口，他回答说，他利用现有的窗口，以尽量减少敲洞。

切记，燕屋设计是根据燕子的习性，并不要为了我们自己的方便。之后我劝他把洞口和漫游室改到另一道侧墙，那边没有障碍阻挡。

This BH located in Klang belongs to my friend’s schoolmate, a four storey building located at hot swiftlet farming area in Klang. The owner designed this BH himself after reading few swiftlet farming books, he started his BH 3 years ago, after 1 year he didn’t get any single nest, and he engaged a local famous consultant to revamp, what that consultant did is installed about 20 fake nests and collected RM5K from him. After another year without any progress, he totally gave up as he already tried everything he could, then he shutdown the sound and let his BH hanging there. Until he met his schoolmate few months ago, I was invited to inspect his sick BH by my friend.

First thing I stepped on his BH I find the roving room and inspect the entrance hole, very little dropping mark on wall of roving room, which means birds were difficult to fly in, I could see the opposite building wall closely from his entrance hole, immediately I found the root cause. He used back window as entrance hole, across the narrow backstreet there is a row of 4 storey building, where the entering flying path was problematic. I asked him why he chose the entrance hole there, and he answered he make use of existing window to minimize wall hacking.

Bear in mind that never make design base on our own convenience but those birds. I advise him to move the entrance hole to the side wall by hacking another one where without obstacle and relocate his roving room as well.
