To me more than one entrance is good but not the one shown in the above picture. This is a bullshit design. The reason is we provide more chances to the birds to enter and fly out from our Bh. I have 2 prooves of my latest design of Bh which gives better significance to the populations of the birds. Despite the disadvantages what is important here is the birds population.Bagi saya Lebih daripada satu lubang masuk memberi kesan yang sangat ketara keatas populasi burung walet menginap dalam Rbw. Pengalaman dalam perladangan burung walet memberi kemahiran teknikal yang berbeza kepada individu dimana susun atur lubang masuk burung adalah sangat penting bukanya bilangan lubang masuk. Sudah tentu apa perkara sekalipun mempunyai kesan negatif atau side effect tetapi mana lebih penting kadar populasi yang cepat atau asyik memikirkan sedikit kerugian,

There were 3 entrance holes in this Bh, different people have different opinions. For me, I always believe in 1 entrance hole. The reason is it would help reduce the time of adaptation and speed up bird population. Secondly, too many entrance holes would cause movement of air which is disliked by birds. It confuses the birds, especially young birds. With too many openings, it shows that the person is indecisive on the best entrance hole placement.
The External tweeters on each entrance hole will confuse the birds, especially new visitors. Often, you could see them flying in from one of the entrance holes and flying out from the others.
