What Really Happen When You Harvest A Newly Completed Nest ???

A question that always come to my mind is what happen if a new nest is being harvested?

If the female owner have two eggs ready to be laid and now her completed nest was taken away how and what will she do?

Someone by a shear accident met a BH caretaker who explained to him on something which we don't bother to find the right answer.

This was the exact word from a message received:

Yesterday had dinner with a friend (a worker in a sawmill factory) who manage his boss BH.
One of the method that he used is to tag which nest start building and watch closely using cctv cameras.  Once they finish he harvested the nest.  Then the bird came back n she seems like crying (maybe) and ask for help.  Then a few birds from beside stop their nest production and come to help her in building the missing nest. Soon the nest is up within a week.  She now can lay her eggs.

Yes all were captured on CCTV cameras.

A very strange story but I believed it is true.

During one of my Swiftlet farming seminar conducted at Time Square Penang.

I was telling my participants about force harvest.

After explaining in great length I open the floor for discussion.

Force harvest is similar like your BH being burglarized.

A strange phenomena will happened where the nests number will jump at least 30-75 %,

One questioned asked was how come and what really causes the nests to shoot up suddenly.

One of the 20 participants help to answer the question.

According to him when his BH was buglarized he took some time to monitor what really happened inside.

His first observation was the first few days the number of birds staying drop by at least 60-70%.

They must have gone to stay at other BHs nearby.

There is a very strong possibility they went there to sort for help.

They must have talk intensely about what happened and the neighbor must have force their young one to come and help to rebuilt the house or nests.

Once they settle in they too will erect nests for their own.

If you have the time please install some CCTV cameras and focus on a newly erected nest.

Once completed you harvest it.

From then on try to observe what exactly happened.

I am sure you will find the answer.
