Serins are very small finches with streaked greenish yellow plumage, similar to Siskins. Males have yellow colouring on their foreheads, throats, necks, chests, neck rings and eyebrow stripes. Females are darker with more streaking and less yellow colouring. Adults of both sexes have yellow rumps, though juveniles do not. Serins’ tails are uniformly dark and their wings have no whitish wing stripes. Their legs and irises are dark brown, and their beaks are dark.
Serins are busy birds, constantly taking flight and flying with an undulating flight pattern.
