NestWatch, the citizen science project!
We look for cavity-nesting birds in trees as well as in nest boxes. A pair of Downy Woodpeckers has been excavating this hole overlooking the feeder gardens. Both will work at the nesting hole for up to three weeks. Their intent is to make a cozy cavity up to a foot deep in which to lay their eggs. They will line the bottom with woods chips. "Downies" usually lay 3 to 8 eggs; the eggs are white so the parents can see them in their dark cavity.
