Pls see attached files.
pls indicate the west n north.
2nd floor shouldnt install full length wall at the air well.

if u study the design carefully, without the full length wall v still can manage to block the sunlight.
new bird will be afraid to venture further in n down for the new bh.

The staircase side of the bh is facing west. So for the 2nd floor, what is your recommended design for the wall? Block half and the other half remove the drop down partition? Initially the drop down partition was only 2 ft, but because of the light, I have to increase it to around 4.5 ft drop.

Xunji, Tuckfook,

Thanks for your feedback. It gives me some ideas to work on.

My BH is located near a river on swampy land. The taller trees around the bh have been felled. The BH is next(500 - 800 m away) to a sizable and successful competing bh which is a couple of years old and my LMB direction is copying that BH's direction as well. The location itself is within 1 to 2 km of swiftlet central , ie the town. The town is just across the river.

I briefly opened the adjacent hole previously but I found that the birds are entering though one hole and out the other. Perhaps I should reduce the size of the hole (which is easily done as the hole size is regulated by a sliding door. When I don't use that hole , I just slide the door to close off the hole).
