Those who already operated their BH for some time and wanted to see more nests I can assure you that by installing a few hundred fake nests will get a faster result.
Why do those swiftlet loves fake nests?
You can think of some reasons on your own.
I have this feeling that they are lazy like most of us however they wanted to mate (make love as quickly as they can).
In swiftlet world once the female eggs are fertilized ( those sperms reached the egg and fertilized) the two eggs will be ready to be laid within 6-8 days.
Yes 6-8 days after fertilization the female need a nest to lay the two eggs.
As such she will not allow the male to copulate unless or until a nest is partially ready to receive her eggs.
If not she will need to use other nests.
To comply to the female birds requirements the male will search for a suitable location where he can erect a partial nest somewhere and it must be a quick one.
Erecting a partial nest on a fake nest will take a very short time as compared to building one on the plank without the assistance of a fake nest.
The male will use very little saliva to get what he wanted (sex).
The moment the female swiftlet check the nest on the fake nest and approved the partially finished nest she will quickly allow the male to couple her.
So that is why a fake nest will make the life of a new couple very sexiting.
If I were those male swiftlet I will do the same.
When my hormone is ready and my sex organ is hardened I wont want to spend too much time in getting my partner to say please make love to me.
The same goes to those male swiftlet.
So if you understand the above explaination you need to quickly buy those styrofoam and cut them into triangular and rectangular.
Install them as many as you can and I might want you to spray some super pheromone on each of them.
I can assure you that within a very short while you will see more and more of those fake nests will be occupied.
Try to put aside about nests quality but get them to be your tenant first.
Once they have utilized the fake nests remove them one by one.
If the total nests in your BH crossed 500-700 nests, you can remove all the fake nests.
The huge number of nests will pull more birds from your neighbors.
Those fake nests is of little use by this time.
However if you have difficulties to populate certain area you might want to let those fake nest be not removed.
Learn how to use these simple gadget properly and know how to get more nests inside your BH.
Try not to question about the nest quality.
You should think more about getting your BH populated to the maximum.
The nest quality is second.
Trust me fully and I am sure you will later realized that the fake nests are your friend.
They help you to increase the nests numbers.
