Good Morning James, do you have this sound? The name is……
I replied, why?
James, I need it for my farm as my old sound is not attracting as many birds compared to months back when my farm first started operation.
.
Do you know why not many birds coming to play now? They get bored with the sound. This is part of nature and it is call adaptation.
As long there is growth in nests and there is an increase in new spots of bird shits you shouldn’t worry about changing the sound.
James, I want to see many birds come and play.
.
Well this has been a norm for most if not all swiftlets farmers. Seeing is believing can’t blamed them. How about having few hundred birds come and play everyday and they don’t build nest? Have you thought about that?
Swiftlets hearing responses to the frequency 1-16 kHz. With most energy focuses on 2-5khz ( fullard et 1993).
This frequency falls into normal human hearing. The only difference is at which tone, high or low when swiftlets produce the sound of chirping and echolocation.
Therefore if you are experience enough in Swiftlet sound you would be able to distinguish the low and high pitch of the same sound from a single female calling.
The high and low pitches of female calling sound is influenced by the situation, the environment of the farm and the location the bird is in.
If you compare any 2 Cd sounds together you would find that these sounds have different pitches. Eg: chiiit..chiiit… would be higher and longer compared to the other which appeared in different time of the Cds.
What does this means? The high and low pitches produced by the birds at a particular time are influenced by the situation whether the birds being disturbed, frighten, or having some good time, etc.
Most recording of sound are done in farm. The person who is doing the recording has to be careful not to frighten the birds while inside the farm. If it does the recording would contains some of these sounds that you may be surprised that will attract many birds to come and play.
These are not favorable sounds that would help nests growth but certainly would be good for farmers who love to see many birds instantly when they switched on the sound. I always omitted these types of sound from my remix.
Swiftlets live in colonies and they are very curious types of birds. Being their natures of colony bonding and curiosity in them any threats within their boundaries they will fly in to help and investigate. Therefore whenever a new sound is switched on especially with unusual pitch you will see them swamping in to investigate.
For me I will identify and only select those favorable sounds produced by young females and avoid those that are unfavorable. There are lots of works in remixing and re-mastering a Cd sound it is definitely more than just cut and paste.
Re-adjusting the frequency to suit the hearing capability of swiftlets is very important because without frequency there is no sound.
Good Farming all.
早晨好, James，您是否有這個聲音？ 名字是....
我回復為什麼 ？
James，我的燕屋農場需要它，因為与几個月前比较當我的農場首先開始操作， 我舊的聲音不再吸引許多隻燕子。
您是否知道為什麼燕子不再來玩？因為他們對這個聲音已經嫌了。 這是自然的一部分，並且它是適應。
只要是長期有窝的成長和有燕子的鳥糞的增量您是不應該擔心改變聲音。
James，我想要看許多燕子來玩。
這是很普通的，如果不是所有的燕屋主。 眼见為实不能責備他們。 如果每天有上百隻燕子來玩可是他們是不修造窝， 您有考虑到嗎？
燕子對頻率的聽力反應是1-16 kHz。多数焦點在2-5khz的能量 (fullard1993)。
這個頻率落入正常人的聽力。 唯一的區別是在哪口氣，高或低，當燕子制造唧啾叫和回音定位时的聲音。
所以，如果您是够經驗在燕子聲音您是能區別低和高音调與一唯母燕叫同一個聲音的。
母燕的叫聲是在以情況影響到处瀝青，農場的環境，並且燕子的地點。
如果您一起比較任何2個 CD的聲音您发现這些聲音有不同的瀝青。 即： chiiit chiiit…是高和長的比較另外一個CD出现的時間。
這意味什麼？ 由燕子发出的聲音是在于燕子的情況，燕子是否被干擾，是否被嚇唬，或者在有好时刻等等。
錄音多數在燕屋農場完成。 做着錄音的人必須小心不嚇唬燕子，當在燕屋農場裡面时。 如果做錄音會包含其中一些聲音您會发现將吸引許多燕子來玩。
這些不是幫助窝成長有利的聲音，但是要看到許多燕子來玩的燕屋主，就換這些聲音。 我總是剪掉這些类型的聲音的再混合。
燕子是合群的鳥类和他們是非常好奇的鳥类。 是他們的合群的本性和求知慾的本质， 在他們所有被威脅的范围内他們將飛入幫助和調查。 所以，每當新的聲音接通特别是與異常的瀝青您將看見他們將飛入澤調查。
對于我只選擇和辨認年輕母燕制造的那些有利的聲音。 要重新混合和灌錄的CD聲音比剪貼确实是更多的工作。
因為沒有頻率沒有聲音，重新調頻率適合燕子的聽能力是非常重要的。大家有好燕屋。
