Male Reed Buntings have black heads and bibs extending onto their chests, broken onlu by their distinctive white moustache stripes and a white collar round the back of the neck. Their backs are rusty brown with black streaks. They have greyish rumps and wing coverts, and their tertials (the large feathers at the wing base) and the edges of their primary wing feathers are rusty brown. Their underparts are brown with faint streaking.

Females and juveniles are similar in appearance to Little Buntings, but they have rusty brown wing stripes, greyish brown colouring on their cheeks, convex profiles to the upper edge of the beak, and broader and less distinct streaking on their flanks. Reed Buntings have dark brown irises, beaks and legs.
