I have received many emails from my readers regarding about Sound Test.
Lets get some understanding about the sound itself. Most sound that are fixed at the entrance of the bird house to attract birds are called external sound.This sound comes with many type of chirping sounds, some consist of male aggressive sound, female heat sound, young birds sound, etc.
These sounds could also be used for Bird Test as well. If the time of testing is not right or the season is not right the birds may not respond, even they responded the number may be low. This means when the Bird Test is done during the noon where the birds are more eager to look for food and if a female heating sound is played they may not respond to the sound as they are more keen on filling their stomach.
Therefore, some have came out with sound that are so tense that even filling the stomach is secondary, this is call STRESS sound, that will attract birds from far away. Therefore this sound was created specially for the purpose of Bird Test.
So to all readers never put or play Stress Sound in your farm. Stress sound is designed for Birds Test only to attract as many birds as possible to a particular area to survey whether the area is potential for farming or how many birds are around that area .This will help in decision making and feasibility of investment.
Most got attracted by the number of birds they see. Those who know about bird sound know what I mean. Playing the Stress Sound in your farm in no time will make your birds leave your farm for another farm. Initially you would see many birds come to the source of sound curiously, months later the population will reduce. The reason why birds are attracted to the Stress Sound, it is because swiftlets are colony in character, if a member being attacked it will produce a Stress chirping sound. If any groups are around that particular area they will fly down to help or investigate.
Therefore Stress sound will attracts many birds but putting in your farm is disastrous. I have seen many doing it without knowing the consequences. So beware of what sound to play in your farm.The safest is to play a good or a normal bird chirping that have female and male sound. That is the best bet and you won't go wrong.
