I am not going to worry about them. The first year we lived here, they built a nest under the deck, on top of a rolled up garden hose. Flew out every time someone walked on the deck. Next year I saw them trying to build a nest on a round outside thermometer, so then I put up the platforms for them, tucked under the eaves so they stay nice and dry.
They are like fussy little old ladies, always getting upset about something. One time we were sitting on the porch and one of the fledglings flew over and sat right near us. The 2 parents were farther away, worrying and squawking like crazy.
I love watching birds. Even phoebes that aren't beautiful or melodious. Today I looked out on the deck and there were 2 nuthatches very interested in a piece of rope that was out there, picking at the raw end to get some fiber for a nest. I think I will put out some yarn bits for them.
