Yellowhammers have brownish streaked backs and reddish brown rumps. Their tails are longish with white edges. Their colouring may vary considerably between individuals. There is always some degree of yellow colouring on their heads and underparts. Juveniles may only be slightly yellowish, but mature males may have more extensive bright yellow colouring, especially on their almost totally yellow heads. Yellowhammers’ underparts are varyingly streaked, with females and juveniles having the most streaks. Their legs are pale yellowish brown, their beaks are bluish grey with a paler lower mandible, and their irises are dark brown.
