Adult male easily recognized by its red head, chest and rump. Females and juvenile males may be mistaken for House Sparrow or Corn Bunting, but are slimmer with shorter and deeper bill. Juvenile plumage olive-brown with dark streaking and buff double wing-bars. Posture often erect, but with short neck, making the bird seem long-tailed. Heavily undulated flight.

Song very characteristic. A melodious, pure and short whistle, often rendered as "pleased to meet you". Each note with a smooth gliding change of pitch. Number of syllables may vary. Contact call a short ascending "hueet" resembling Siskin in timbre.
