You Can See The Scars On The Wall Of These Buildings !!!

All in all due to lack of knowledge about those wild birds.

Have a good look at this picture and tell me what do you think went wrong?

The BH was designed with a veranda on the top.  This is where those young swiftlet will enter the house from the top entry and fly down via a tunnel.  But I believed they refused to follow what it was planned for.  After a few months there was no tenant so the owner opened a new entry hole at the side. A big hole about 12 feet by 16 feet, I think.

This BH have the some problem.  In fact she was about 100 meters away from the first BH.

Facing the same problem where the original top entry tunnel was not working.  The owner resort to opening three new entrance hole at the side.  If you look carefully this was the second time he opened the side entries.  The first was along the tunnel then he shut them and moved inward in the nesting room.

Assuming that the new entrance holes now works, my conclusion is that the swiftlet in this area prefer the side entry not the top entry.

I recalled the observation made in the town areas nearby these two BHs the most successful BH was using the side entry.

The lesson we learn here is that before you decide to opt for any type of entry please do some investigation.  Get to know those birds and where do you think your tenant, mainly young birds, will come from.  They normally will come from the most successful BH(s) in your area.  Look at the type of entry of these BHs and choose exactly like them.

What if the number is nearly equal?

Be my guess just think of the best solution.
