Both internal and external sounds were dead and the roof was blown away due to heavy storm.
What do you think can be done to salvage this BH?
I need to view from the outside and the inside.
I also need to look at the BH orientation.
Need to find out its main entrance hole, its facing east or west.
Need to also check the condition of all those nesting planks and perhaps look at the orientation of every floor.
Where the birds are currently staying and where are the LAL holes.
There seems to be no partition on those floor seen in the pictures given.
The number of air ventilation holes are too many and were not covered with any extension pipes.
Just by looking at these pictures I can guess what can be the main reasons.
First it have to do with the brightness.
If there are no walls and those air ventilation holes are not properly covered you know how bright the nesting rooms will be.
I can safely predict that the LAL is not properly located.
The nesting planks seems to be too wide and thus reduce the number of nest per square foot.
