Blue Tit

 
 
 
                Blue Tits are small birds with strong bills. One of the most noticeable features is the strong head pattern; the dark blue-black eyestripe and the brighter blue ‘skull cap’ are set against the white cheeks and forehead. The blue-green back becomes a brighter blue on the wings, while the underside is a bright lemon yellow. Although male Blue Tits are usually brighter in colour than the females, this difference is often not apparent in the field. Young Blue Tits are duller in appearance than the adults and have pale yellow, rather than white, cheeks.
