Breeding season is April to May. Nuthatches nest in holes in trees, often plastering up the hole with mud if it is too large. They lay 6-9 eggs, which are incubated for 14-15 days. The chicks fledge after 23-25 days. The nuthatch will hiss at any predators who near the nest. Most juveniles settle within 10km of where they were hatched.
