I was concerned because I hadn't seen the house finches around the nest cup in front of the wild bird store. Last year when she nested in there you could always see when she was incubating. After the store closed, I set up the ladder to look at what was going on. As I poked my head over the cup, the female flew out. Apparently she nested deeper in the cup so she hunkers down when incubating. She now has five eggs!
