Received the above picture from this poor BH owner.
"Pak Harry again submerged."
This was his second time.
The first time happened last year and the water level was about 8-9 feet high.
This time he is not so sure.
So far have not entered and waiting for water to subside.
I was engaged by him to revamp the BH and the nests numbers were growing steadily until submerged.
He is fully stressed and very disappointed but there is nothing much he can do.
The big problem will be after the water level subside.
Usually the number of birds returning home will be very little.
They might fly to other places and never return home.
Mainly due to lack of food.
Once the ground is cover with water there will be little insect.
No food no swiftlet.
Look at some pictures taken last year.
