1961 · Short film · 11 min
Synopsis
Shows selection of nest site by a pair of black woodpeckers, digging nest cavity in a tree trunk, and then care of young through various stages to fledging. Both parents participate. One scene illustrates pre-emption of partly constructed nest by a pair of predacious birds, but woodpeckers regain nest after intruders leave. Scenes photographed inside the nest show feeding of young, cleaning movements of parents, sitting on the brood, and general development of young
