There Are So Many Birds In The BHs But Not Many Nests, Why Pak Harry !!!

Something that seem to be quite common in Vietnam.

The number of birds inside the house is by the thousands but the nests on the nesting planks are less then a few hundreds.

The first case was a BH owned by the King Shrimp producer.

From his evening counts the number of birds was at least 2,000 entering his 100 days old BH located in the east of HCM city.  When entered for the first time after the shut the door off of 100 days the number of nests on the nesting planks was about 100.

He suspected that it was due to those mulfunctions humidifiers and his water pump.

I think there must be something more to that.

The second unit was about 5 minutes drive from Caravalle hotel.  The owner's son took soom time to visit his BH today and after following my advise plus playing my Black cloud sound, the number of birds entering were at least 3,000 birds.  This was after less then 2 years playing my Black Cloud.  Before that there was nothing.

I was given a chance to enter the BH and the number of birds inside was at least 600 to 700 flying over the place.

To my surprise, the son told me that he can only harvest less then 700 grams a month.  That is something wrong with this BH, I told him.

So what do you think might be the possible problems.

The humidity looks good (floor were wet), the temperature was also good (if not they will not even bother to stay), the darkness was within range.

What can be the cause of your tenant not wanting to pay their monthly fee?

I am of the opinion that they might be too young birds who are not ready or perhaps matured to find a parner and start making love.  If it is so why can't the owner seduce them to find a partner and quickly mate?

The best is to play the righ internal sound.  I suggested to the son to look into the possibility of testing a number of internal sounds available one by one.

The best is to assemble about 5 to 6 good sounds and test them for at least 1.5 months.

Before starting the first sound he should take some nests count check.  Take those counter and take note of the total number of nests in the house.

After every test, he can start counting again.  Compare the number and if there is a different then log them inside a book.

Once he finish all the sounds selected he should choose the best among the 6 sounds.

One possible reason could be the type of planks used.  In Vietnam, red Meranti is not easily available.

I think he should consider importing a few, say one ton (1,200 feet), and install them onto the current nesting planks using screws attachment.

Just focus on one floor which have the least number of nests.

Do the same nests counts before and after.  After say 3 months if they love meranti then why not import more to cover the whole planks in the house.

It is worth the hassle and hard works.  If he can increase the percentage from current only 20% to 50% or higher, it worth every penny, I assured him.
