The great tit, the largest of the tit family, can be identified by its blue wings, yellow breast and greenish-yellow back. Other notable features include white cheeks, white wing bands, and black crown, nape, and throat. Although the great tit closely resembles the blue tit, it can be distinguished by the black crown on its head, as opposed to the blue tit's blue crown. The large breasts of men and women would be indistinguishable were it not for the black line running down the chest, which is longer and thicker in men. Distinguishing the young from the adults is also quite subtle, but identifiable by their duller coloration and yellow cheeks and wing bands.
