Swiftlet Preferred Larger Entrance Hole !!!
During my recent revamping job in Kedah I can safely says that one of the main reason why the neighbour's BH is doing very well was the size of its entrance hole.
The two units were erected by the same contractor and just about 100 meters apart.
They went put into operation on the same day, according to the owner.
After 20 months into operation his BH was with about 300-400 nests while the sick BH was only having 44 nests.
The rest, from view outside, were the same except the main entrance hole of his was larger about twice as big as the sick BH.
I told the sick BH owner that he needed a larger entrance hole and the recommended size was 3 feet wide by 4 feet high.
I wanted to proof that I was right and managed to take some video clips showing how easy it was for those swiftlet to fly in and out as compared to prior to its enlargement.
Have a good view of these two clips and you might observe the differences.
After enlarging operation to 3'x 4'
Very clear indication of how important is the size of your entrance hole.
To those who are new you might think or being wrongly advice about those negative points example to much light and air flow but if you are an experience person you will figure out how to minimize the light and air flow by erecting those partitions.
The key point here is to let those wild birds feel at ease when entering and leaving.
There is no use of blocking them from smooth entry into your expensive BH.
