Our house has a narrow channel approximately 3" tall which runs along one side (it's to ventilate the loft).
A year ago, we heard noises from above a ceiling and found that jackdaws had managed to gain entry via this slot and our pantiles and this took them into our loft.
We have had no help from the RSPB (who couldn't come up with a plan except to paint the exterior with something the birds disliked the taste of) or indeed roofers, who put in mesh to keep the birds out. Within two days, the birds, working in pairs tore the mesh out. The roofer returned, redid the work and assured us he had made the area jackdaw secure. Well, he had - for another two days - before the jackdaws, working in a team of three (they had brought in an apprentice) ripped the 'secure' mesh out.
My husband spent several months (on and off! I didn't keep him chained up until he had finished!) putting in panels of wood from the inside of the loft into the space at the edge to try and stop them entering. It is impossible for him to actually reach the slot/edge of the loft due to the angles, so he was working blind.
Incidentally, the exterior of the house is 30'+ high as we are in a hill and he's too old to balance that high on a ladder to work from the outside.
Once again, these clever corvids circumnavigated all his efforts and had made a hole with their beaks for ingress. They had a very comfy snuggly winter.
We have given up. It is breeding season and of course we don't want to harm the birds or break the law but we do who wonder who will support us if the jackdaws peck through cables and start a fire....
There seems to be no way to rid us of these birds.
Ideas anyone, please?!!!
Ours has that space too but it is filled with sturdy metal grids - apart from one part which the builder missed. Blackbirds managed to get in and once, when I climbed the ladder to go into the loft, one whizzed past my head. I nearly fell down the ladder.
DH filled in the gap after they'd gone but I think sparrows can just squeeze through the gaps between the bars.
A baby sparrow came and sat just above my head on the trellis yesterday, it was looking for its mother. It was so tiny and trembling, obviously just fledged but looked too young and fragile to be out of the nest.
The mother did come and collect it.
