context_page_description: Nuttall's woodpecker is a species of woodpecker named after naturalist Thomas Nuttall in 1843. They are found in oak woodlands of California and are similar to the ladder-backed woodpecker in both genetics and appearance.
context_section_description: Nuttall's woodpecker has black wings and tail feathers with white barring. On the ventral surface, colour is white with black spots and barring. It has a black forehead with white streaks on the sides and an unbarred black region at the top of the back. Adult males have a distinguishable red crown which females do not. However, this physical feature is present in the juvenile of both sexes. They have zygodactyl feet and stiff tail feathers which allows them to maintain a vertical position on trees; typical of woodpeckers. The mass of the Nuttall's woodpecker ranges from 30 to 45 g (1.1 to 1.6 oz), with a body length of 16 to 18 cm (6.3 to 7.1 in).
