Then celticdragonfly spotted me on the ladder as I unscrewed the covers for each duct, slid in some screening, and screwed them down again. We’d officially evicted the birds.
Of course, this meant we had a family of homeless birds on our conscience, right during nest-building season. So celticdragonfly had picked up a birdhouse as a resettlement zone for the critters we’d booted out. A little more ladder work and it was nailed to the eaves, safe from predators and weather. The bird feeder went up in the back yard and we were done.
Cute vermin are way too much work.
