Two-barred Crossbills are slightly smaller than Crossbills and have more slender beaks, which are still relatively sturdy and crossed. Birds in all plumages have two wide and distinctive white stripes on each wing, broadening towards their backs. Their tertial wing feathers also have white tips. Males are mainly red in colouring, while females are a bright yellowish-green. Juveniles resemble the immature birds of other crossbill species and are mainly brownish-grey with streaked plumage. Two-barred crossbills have brown legs, pale brown beaks and dark brown irises.
