Nuthatches have a long pointed bill and, unlike most small garden birds, appear to have no neck, giving them the appearance of a large head. Their upperparts are blue-grey and their underparts are a buff-orange, which becomes more chestnut on the flanks. They have a blue-grey crown and nape, a black eye stripe and white on the rest of the face. The male has more intense chestnut flanks than the female, and juveniles have less.
