Few readers had called me and asked how important is the intensity of light or the darkest in the farm compared to other micros.
As I had mentioned before every parts of the micro is important and we can't take it lightly. All must be at it perfection! If any one of the other micros is bad it will affect the other.
If you had entered many successful farms you will notice that there are many nests in both bright and dark areas. So what is the appropriate darkness in farm?
There should be areas of bright and dark in farm. In such the birds could have choice to choose whichever areas they wanted.
A gradually bright to dark is very important in farm. Young birds would build nests at the brighter area as they could access in and out of the farm easily.
Experienced birds could build nests everywhere mostly deeper in the farm as they had developed their echolocation ability. So darkness is not an issue here.
This is why most authors of swiftlet farming books would advise bigger entrance hole for new farm and later when population increases the size of the hole be gradually reduce to small. This would reduce the intensity of light in farm thus making it darker. So a very dark farm is not an issue for old farm.
This answered the questions of readers asking “why some successful farms are so dark and some farms are so bright?
It would be wise to have a meter or instrument to check the intensity of light. From here you could write down the Lux recorded in the meter and compare then later if you want to reduce the entrace hole or intended to put up the partition. It will help you to understnat the degree of darkness your farm needed.
Well I guess most out there would tell you how they do it. But they will not tell you why they are they doing it. Just like the above. Perhaps they might not even know why they are doing it.
少量讀者问我光的密度或在燕屋農場的黑暗比其他屋内环境是有多重要。我有提及过，在屋内环境的每個细节是重要的和我們不可以輕地面对它。它必须是完美的! 如果 任何一個屋内环境的细节是不好的它將影響其他细节。 如果您进入了許多成功的 燕屋農場, 您将注意到有許多窝在明亮和黑暗的地方。 因此在燕屋農場里什麼样的 黑暗是適當的？在燕屋農場里應該有明亮和黑暗的地方。 在這樣燕子有選擇他們想要的余地。在燕屋農場里有由明到暗的地方是非常重要的。小燕子將修造窝在更加明亮的地方因為他們可能容易地进出燕屋農場。老練的燕子將修造窝在更深的地方因為他們開发了他們的回音定位能力，燕子可能到處在燕屋農場修造窝。因此黑暗不是問題。 這就是為什麼多数燕屋農場的的作者會勸告新的燕屋農場的入口孔更大， 並且，當燕子人口增加了, 入口孔是时逐漸以后減到小的。 這是因為使燕屋農場將減少光的 密度更加黑暗。因此一個老的燕屋農場非常黑暗不是一個問題。 這回答了讀者的 問題「一些成功的燕屋農場為什麼如此黑暗，並且有些燕屋農場是很明亮的？ 有檢查 器或儀器来测量光的強度是明智的。 從這裡您可以記錄下和以后比較，如果您想要 減少入口孔或意欲要举起分開。 它將幫助您明白對黑暗程度的需要。 我猜測他們將 告诉您怎样做它。 但是他們不會告诉您他們為什麼是做它的。 像在上面。 或許他們也許甚而不知道他們為什麼做着它。祝您好运。
