Smaller than a Great Tit with blue wings, tail and head with white cheeks and white ring around the crown. The underparts are yellow. It occurs in dehesas, pinewoods, wooded valleys and gardens. With its small bill it takes insects from under loose bark and leaves and is able to hang upside down to forage for them. It is a great friend to the organic farmer. It is present throughout the year in wooded areas in Extremadura.
