The wrens continue in and out, cramming stuff into the thatched-sided nestbox. So, if a pair are doing this, does this still mean it could be a dummy nest? One has stood guard as the other works inside.
I know it’s early, maybe the weather has them fooled, like me.
Either way, it’s fun to watch. It’s like a fish on a line…when the rhody leaves “bob,” I know the bird is in…
