The rather diminutive blue tit (Parus caeruleus) has yellow underparts, with a narrow, dark central stripe on the belly, blue wings and a white face, which is crowned with blue and streaked with a dark eye-stripe. The sexes are similar, although females are often somewhat duller than males. The juveniles have a more yellowish face than the adults. A range of clear calls is produced, including a high sisisi.
