We have a robin that epitomizes that term! First, she started a nest on the support beam of the roof of the outside deck - she abandoned that. Next, she started a couple of nests under the deck roof - she abandoned these too.
We figured that was the end of the problem - we don't really like robins above the deck as they make a terrible mess. However, I looked out this morning and there was a robin perched in the same area where one of the nests had been. She was twitching and fidgeting around and had us wondering what she was doing. I went about my normal morning routine and put her out of my mind. Bob called me sometime later and told me there was now an egg on the beam - but no robin.
