Carried out some inspection on the performance of steel plates installed at Kapar BH recently.
I installed about 10 plates inside the BH about 2 months ago and wanted to observe the reaction of those birds.
What I did was to identify 10 candidates (3 top floor, 4 middle floor and 3 ground floor) and carry out the installations.
The best candidate will be those corners with nests and without and young babies.
Those that are empty or with two eggs will be the best candidates.
Once the nests are harvested, the plates will be installed to cover the nest spots.
I need to make sure that the flat area covering the planks are flat by at least 1.5 inches.
My prediction was that once they returned to the same spot they will have no choice but to occupy the meeting point between the plate and the wood.
They can chose the left side or the right side.
The middle curved area will be too smooth and there is no chance to cling onto the surface.
Well let me show you these pictures taken.
Not all are showing positive results.
Out of 10 only 5 with expected result while the rest seems to move to a new location.
5 out of 10 is still a good rate i.e 50% success.
The only setback adopting this technique is its cost.
The plate about 6"X 9" with 4 holes drilled cost about RM9.
The cheaper alternative will be the plastic chain.
No matter what the cost is I think this method is proven to be effective.
