Robin sign of spring

Once again, the Robin that tried to get into my kitchen last year to nest, is back. She keeps flying into my window and has become so used to seeing me she doesn't fly away when I take her pictures close up or open the garden door and try to shoo her away

Last year she was most  persistent and kept flying into the window for a few weeks. I thought that my tomato plants were attracting her as they were right by the window.
