Add Three More Speakers!

After we added three speakers in our roving room, it's still not effective enough!
We were able to pull in birds from outside into the roving room, but they still didn't come down into our nesting room.

On May 13th, my partner, Wor, went in to install three more speakers, two on the north wall and one under the nesting entry. Also he plugged in all the ventilation holes on third floor and second floor to reduce the air flow came inside the building. We left the ground floor untouched and also one on the second floor to let some light in to lure birds down.
Another thing he did was to seal the open roof with wood planks to reduce light shone into the roving room.

After the improvement, on the first day we still couldn't tell whether they were any improvement or not.
But luckily, 3 days after the improvement,there were raining daily, many birds showed up.
Today, on May 15th, we can clearly saw that birds came down from the main entry hole to the front of nesting hole.


The video records clearly showed that the records on camera 4 in front of nesting hole could outnumber the record on camera 2, the outside hole, of which it never happened before.

The problem still that, with so many speakers in the roving room, the sounds in roving room would be much louder than the sounds inside the nesting room. So birds would rather stay in the roving room rather than flying further into nesting room. These two videos will show you what I meant.







Next step is to install more speakers in the nesting room to pull the birds into the nesting room.
