Who's sitting on the nest?

It is April, so we assume Ethel and Ernest have mated this spring, and that Ethel spends most of her time sitting on the nest until her egg or eggs hatch. But earlier this week I saw her on the lamp post again, so perhaps Ernest was egg sitting. Saw him earlier, however, out fishing in a drizzle. Will check in with the other blogger who is keeping sight of the nest and report anything interesting he has to say about the little family.
