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.

Further Improvement

Last week two improvements were made:

On April 31st, my partner wanted to add a partition to facilitate the birds flying into second floor.
Two days after the change there is no adverse effect on the rate of incoming birds. They still came around the house three rounds a day, morning, noon and one o'clock. The problem was the amount of birds outside the house, in front of the entry hole were so plenty, but only less than 10% flew inside the house, and even worse, less than 10% flew into nesting room!
On the third day after the change, the noon and afternoon birds were disappeared and they came around 6.00-6.30 pm instead. Same symptom, plenty on the outside, very few inside!

So on May 4th, my partner went in again to increase two more tweeters inside the nesting room facing to the nesting entry hole. My observation was once birds were inside the house, they flew into the nesting room more smoothly, less flocking outside of the entrance hole.

This video showed that they flew into the nesting room faster than before with the help of two more tweeters inside.



On May7th, my partner went to installed three more tweeters on the roving room to help pull down the birds. But I guessed they weren't effective enough, the same problem of very few birds fly inside the house is still there. The majority of birds were circling inside the BH behind the entry hole a few seconds and then flew out. What a heartache!
