Bird proofing is normally good for 20 plus years but this proofing has not lasted that long to due to being only spiked for the leading edge of the bay window. The rest of the window has had balled up chicken wire pushed in.
This has become compressed over time or possibly by the pigeons activity to become a suitable nesting site again.
On a bay window like this we strip off all the old proofing and spike the entire flat edge. This provides the pigeon no possible place to nest.
When we carry out our proofing work we always make sure we fully disinfect the area after the old proofing is removed. This kills all avian pathogens and parasites.
