Red-bellied Woodpeckers love oranges!
You can nail an orange to a tree, or place it in a suet cage and Red-bellies may come visit, dipping their bills into the juicy pulp.
They nest in cavities such as tree holes or birdhouses
One might show up at your bird feeder if you stock it with sunflower seeds
Red-bellied Woodpeckers could be called the orange juice woodpecker since they seem so fond of orange halves. When we are in FL, it's easy to attract them by putting out oranges on a tree or other container. At your bird feeder you can attract them with sunflower seeds, nuts and suet.
Red-bellied Woodpeckers can excavate a nest hole in a living tree, or excavate in a tree that has recently died. They will also nest in a birdhouse with the right dimensions. As part of courtship, male and female mutually tap on a tree, with one inside a potential nest hole, the other outside. We have seen this a number of time in Florida and it's fun to watch. They lay 3-8 white eggs, incubate them for 12-14 days, then the nestlings will fledge at 25-30 days.
Here in NH, a Red-bellied Woodpecker is an uncommon sight and we only see them several times a year. However, Red-bellied Woodpeckers seem to be making more incursions into NH and other areas even up into Nova Scotia. It is believed that Red-bellied Woodpeckers are undergoing a range expansion to the north and west. They breed over much of the eastern half of the country and are thick in the Southeast, but have not been that common in the far upper Midwest, or northern New England or the Canadian Maritime Provinces. Maybe that is about to change.
Hope you get to see them in your area soon.
