This video from the USA says about itself:
18 June 2016
Amazingly the Red Bellied Woodpeckers have four new eggs in the nest box when I returned to Florida. The first three fledged just two weeks ago. I can not be entirely sure, but it is likely this is the same pair that has decided to mate and raise a second brood right after the first. Perhaps because they like the house and food conditions are good. Woodpecker babies take a long time to develop before fledging. At this rate they will be fledging perhaps in late July or early August. This is rather unprecedented in my experience, but at least this nest box is in the shade all day because it is hot!!
