The Nuthatch is the only member of its genus or family found in Finland. These small, sturdy birds can climb on tree trunks and branches with great agility, facing either upwards or downwards. Their upper parts are bluish grey, and their underparts are white. A narrow black eye stripe runs from their beaks to their necks. Their undertail coverts are reddish brown with white tips. Birds of the nominate race have more extensive reddish brown colouring on their flanks. Birds of the more easterly race have white markings on their forehead and above their eye stripe. Nuthatches’ legs are brownish yellow, their beaks are dark grey, and their irises are dark brown.
