Hint of spring is in the air, at least the singing of returning birds can be heard, like the red-winged blackbirds, killdeers, robins and the sweet sound of the Eastern Bluebird.
Soon, when the female bluebirds arrive, the male will put on a display at the nesting boxes. He will bring nesting materials, usually dry grass, into the nest and then perches on top waving his wings. And that is about his only contribution to the nest building as the female does the nest building and incubating the eggs. But I have seen the female reject the male’s nest choice and he has to go house hunting some more.
