Today we visited Fonmon Castle in the Vale of Glamorgan. They would like some Swift boxes put up on the castle. We saw plenty of House Martin activity in the window recesses of the 11C century castle. One wonders how long House Martins have been using the site for nesting?
Swifts are known to use the river valley below the castle for feeding and there is scope for some boxes at the site. A complication is that the building is grade 1 listed and we would be unable to drill in to the fabric. We identified a niche on the north wall of the castle that might be suitable for a bank of boxes, which might possibly be braced in to the gap, without disturbing the fabric of the building. There is also an electricity supply nearby, so a call player might be feasible.
It's early days yet but we are hopeful of getting something started at the site.
