After all the modification, the current design is as the following:
A friend recommended us to change the partition as the picture below, as the above partition will block the flying path of birds for easy in easy out. The new partition will help boost the no. of birds staying on third floor, as this third floor area will be more private to birds. But my partner does not agree to, ego, ego, sigh!
June 21st, 2011. After a long discussion followed by a summary write up of what have been done so far and what are the results, and my 6 convincing emails to my partner. He agreed to take out the partition that blocked the flying path of birds into second floor. But he still do not agree to put on a new partition as recommended by a friend. Need more time to convince him, I guess.
After the partition was taken out, on that same day during the whole afternoon, I saw the highest number of birds inside my BH! Many birds also flew down to second floor freely. Checking with the CCTV records, it was confirmed that the no. of records inside the house for both third floor and second floor were the highest ever! Birds count on that evening is 33, almost 100% increase from the stagnant no. of 18 for 6 months!
So now the current plan is as below, much easier for birds to fly in and out. The partition was a big mistake!
