Being Blacklisted By Those Swiftlet !!!

Is it possible your BH being black listed by those wild swiftlet?

I have never come across such an event in swiftlet farming before but ..........

Usually those banks or money lander or IRS will black list you from taking any loan or travel overseas if you defaulted any loan or mortgage payments.

But this week I received the following:

Brother Harry,

May I check with you please, What you should do next when your BH seems to have been blacklisted by birds ( they don't bother to enter at all now although they did enter previously ) despite the fact that you have made some internal changes and sound changes as well ?

Thank you.


 Never experience such a drastic phenomena collectively done by those wild birds.

My opinion, might not be right always, on the possible reasons are:

1) There is or are some gross mistakes that the owner was not able to determine.  Usually the internal temperature, the darkness and humidity.

2) The next could be the sound played.  He need to regularly check on the external and internal sound that he is using.  The sound quality, the setting on the amplifiers, the sound distribution from the outside into the house and until the back of the house.

3) The tweeter arrangements at the entrance window might be causing the birds confused and don't know how to enter the house.

4) The flight path from the main entrance hole into the nesting room(s) might be too tough for the birds to fly in and out.  Once they entered and they cannot find their way into the nesting room(s) they will shy away from the house.

5) There might be a predator that must have scared the birds before.  The biggest culprit are owls.  Once they attack you BH they leave their marking especially droppings (shit) that give the bad signal to those swiftlet.  The area where those owl used to purge need to be carefully cleaned and spray with swiftlet aroma.

6) High time to get a professional who can evaluate the real situation and comes out with the most practical solution. Contact those whom you know can help to identify the exact problem and get someone to carry out the installation of the recommendations.
