Amazing pictures send by a friend from Pahang. Night Hawks
caught outside a Stand alone Swiftlet farm.
He has observed them for many months finally a few were
caught. The Night Hawks were trapped by using fishing nets.
The Night Hawks came during the dusk and dawn. He saw them
attacking the Swiftlets outside the entrance hole when they were circling
before diving into the farm.
Night Hawk diet mostly consists of big insects. Look at the
beak it resembles Swiftlet beak a very curve and sharp beak. It has been
documented, occasionally they would eat small birds (preferred diet are
insects). They grow up to 18-28cm depends on the species.
My friend saw them attacking some of the Swftlets outside
the entrance. The bird population has declined and he decides to trap them.
驚人的照片從彭亨州的一位朋友寄來的。夜鷹在獨立燕屋農場的外面被捕抓到。
他已經觀察了它們有好幾個月了，最終也抓到了。夜鷹是通過使用捕魚網才抓到的。
夜鷹是在黃昏和黎明時分出來的。他看到它們攻擊在入口洞外的燕子，當燕子們在盤旋要潛入燕屋農場之前。
夜鷹的主要食物包括大型的昆蟲。看看那鳥喙它類似燕子的喙，非常彎曲和尖銳的喙。它曾經被記錄，偶爾它們會吃（首選的食物都是昆蟲）小型的鳥類。它們可以長到18-28公分大，看看是那個種類。
我的朋友看到它們攻擊在入口洞外的一些燕子。燕子的人口下降，他確定要裝陷阱來困住它們。
(Fierce red eye .....doesn't it look like the CCTV Led
light)
(兇猛的紅眼.....看起來是不是很像閉路電視的LED燈)
The name "Night Hawk" tells all. From the picture
it clearly shows they are active during night (low light). The color of their
eyes indicates this. Their bright red eyes show they can see extremely well in
low light condition. It is like infra. Talking about that it reminded me about
an article I had written many years ago regarding the good and bad of having
CCTV in Swiftlet farm.
I have said the red LED lights on the CCTV resemble the eyes
of predators. Having CCTV at the roving may deter Swiftlet from flying into the
farm especially new farms. CCTVs installed in a corner of the roving resemble a predator ready to ambush. It would frighten
Swiftlets.
它的名稱"夜鷹"就告訴一切。從照片可以很清楚地表明它們在晚上(低光線)的時候是很活躍的。它們眼睛的顏色指示這一點。它們明亮的紅色眼睛顯示它們可以在低光線的情況下可以看的非常清楚。它就像紅外綫。談到這一點，它提醒了我一篇我寫了很多年前的文章，關於使用閉路電視在燕屋農場的好與坏。
我說過，閉路電視的LED紅色的燈就好像捕食動物的眼睛。在環繞區裏有閉路電視可能阻止燕子飛入燕屋農場特別是新的燕屋農場。閉路電視安裝在環繞區的角落類似于準備伏擊的食肉動物。它會嚇倒燕子。
Have you ever wondered why the eye of the Hawk and the LED light are of the same color …hot red ( same tone of red)????
Because both could see in low light condition, even in total
darkness. Swiftlet cannot see in total darkness therefore they use echolocation
(the clicking sound). Swiftlet eyes are not red they are black color. If
Swiftlet eyes are red they don't need to use echolocation.
你有想過爲什麽夜鷹的眼睛和LED燈是相同顏色的....
火紅色（同樣色調的紅色）？？？
因為兩者都能在低光線的情況下看的見，即使在完全的黑暗中。燕子卻不可以在完全黑暗中看得見，因此它們使用回聲定位（卡嗒的聲音）。燕子的眼睛不是紅色的，它是黑色的。如果燕子的眼睛是紅色那麽它們就不需要使用回聲定位。
儘管有人認為他們的燕屋農場一直在使用閉路電視很多年了，他們也沒有遇到任何問題。也許他們的燕屋農場位於沒有捕食動物的地區。你想要承擔這個風險嗎？
They were caught at about 7.20pm. Fiercesome eye......
Good Swiftlet Farming All!
它們是在傍晚7.20左右被捕抓到的。兇猛的眼睛......
好燕所有 ！
