Why birds abandoned their nests that they had spent weeks to build? There are many reasons for this.
.
Some may argue that it has got nothing to do with the environment because if the environment in not good then the birds would have not built the nests in the first place.
.
They have a point there, bare in mind being Micro or Macro things constantly change. A farm could not remain the same over a long period of time. What was good then could be different now.
.
There are hundred of things that may affect the Micro & Macro example-1) Micro, as the population of birds increased the amount of birds dropping also increase. This would push up the RH in farm. So it changes the Rh. So you see things changed over time. 2) Macro, over the time more developments and more new farms, this affect the food where the Swiftlets feed on.
.
In such challenging environment a farm could not remain the same over time. Somehow a good farm may turn bad if the changes are unnoticed. To counter these changes one has to constantly observe the Micro & Macro.
.
We certainly can’t leave the farm as it is. Any short coming must be rectified immediately. The earlier we noticed the changes the better it is.
.
No point of wait and see this doesn’t help at all. My advice is all farms should have all info recorded. The Temp, Rh, No of new nest & nest making, etc. Any significant changes will tell you that something maybe wrong some where.
.
Good Luck & Good Farming.

為什麼燕子放棄了他們度过几星期修造的窝？ 有許多原因的。 也許一些争辩说，这些與環境沒有关系，因為，如果環境不好燕子根本不會首先在那裡造窝。 他們也有 點理由，需要注意的是, 屋内和屋外环境是經常改變。 燕屋農場不能同樣保持在一個 長的时期。 什麼是之前好的現在可能是不同的。 有一百件事也許影響屋内和 屋外环境的, 例子:
1) 屋内环境，當燕子的人口增加了, 鳥屎也相當增加的。 這在燕屋農場RH也將增加。 因此它改變了Rh。 因此您看隨著時間的推移被改變的事物。
2) 屋外环境，随着时间更多發展和更新的燕屋農場，這個影響燕子的食物。 在這樣富 挑戰性的環境裡燕屋農場不能隨著時間的推移保持同樣。 莫名其妙地， 如果變動是未被注意的，一個好燕屋農場也許變壞。 要抵抗這些變動, 一必須經常觀察有一百件 事也許影響屋内和 屋外环境。 照样的，我們不可能不理会燕屋農場。 其中任一必须 立刻矯正短來。 我們越及早注意到變動是越好的。看着等根本幫不上。 我的忠告是所有燕屋農場應該記錄所有信息。温度， Rh，沒有新的窝& 做窝等等。 所有重大的變動將告诉您某事可能冤屈一些的地方。 .好运& 好燕屋。
