Yes, it appears to be jackdaw nesting season and thanks to encouragement of our neighbours (sorry USA readers, neighbors) there is a thriving flock and thanks to our neighbors finally understanding hosting them in one's loft space is less than ideal now look to other locations for a place to nest.
The next best nest site appears to be under my solar panels so the ritual of shooing the birds away and making sure that the pile of twigs doesn't get the opportunity to become a nest has begun.
