The Izu thrush, named after the group of Japanese islands on which it occurs, has richly coloured plumage; brownish-russet on the upperparts and orange-red on the breast and flanks. The wings and tail are blackish, and the centre of the belly is white. A yellowish bill and narrow yellow ring around the eye contrasts with the male's black head and upper breast. The female has a dark brown head and white throat, streaked with black. Juveniles have brown plumage with buff streaking on the upperparts (2).
