When he looked in, he saw it was a nest and in there were the chicks of a woodpecker.

Woodpecker chicks normally eat small caterpillars, but they can even be fed chicks from other birds!

Woodpeckers nest in cavities, nearly always in the trunks and branches of trees, well away from the foliage. Where possible, an area of rotten wood surrounded by sound timber is used. A typical nest has a round entrance hole that just fits the bird, leading to an enlarged vertical chamber below. No nesting material is used, apart from some wood chips produced during the excavation; other wood chips are liberally scattered on the ground providing visual evidence of the site of the nest.

A pair will work together to help build the nest, incubate the eggs and raise their altricial young. However, in most species the male does most of the nest excavation and takes the night shift while incubating the eggs. A clutch will usually consist of two to five round white eggs. Since these birds are cavity nesters, their eggs do not need to be camouflaged and the white color helps the parents to see them in dim light. The eggs are incubated for about 11–14 days before they hatch. It then takes about 18–30 days before the chicks are fully fledged and ready to leave the nest. Eggs usually are being
