Some interesting bird house in indonesia

During my trip this month to indonesia helping few indonesian friend revamp their Sick bird house. I took some photo of the intereting BH near the location. You can see they have so many design and patern.

 Look closer you will notice this owner move the entrance hole from top to down roof level. This owner have doubt of building a monkey house. Do you think monkey house are must , why small number of people prefer no monkey house, what are the pros and cons !!, we will talk about this in future.

 This BH really huge, with only one entrance, imagine if this BH really success.

 99% of indonesia BH they really dont know what they are doing, I found that they only follow other, but  most of them have at least few hundred nest even you do it wrong cause the number of bird there are huge and the food available also adequate for the bird to populate.
