Most 1cy birds should be left unsexed, while the vast majority of 2cy+ can be sexed according to the below.

1cy: According to Svenson (1992) birds without any black on head should be left without sex, while birds with rather much black in crown and nape should be males.

2cy+: Males have a rather clean white forhead and a lot of black showing in crown and nape. Females have a darker grey forhead and no (or little) black in crown and nape.
1cy male September. Birds with rather much black in crown and nape should be safe males. More intermediate individuals are best left without sex. [1ET81832]
