I did a nest count on end-Jan about 1 month after I hacked the wall to made the roving area bigger, no increase in nests count. When I did another nest count on 19-Feb, I found 4 new nests. It seem like the new design help to attract more birds.
I still find that the light is too bright. So, during this CNY, I used unused banner to made a partition about 13 feet from the entrance hole. Just use screwed to screw one end of banner on plank and used bricks and sand board to pull the banner at the other end. Easy and fast.
