Large thrush, adult rich brown marbled with dark marks above, pale with black scaly marks below. Larger Bassian Thrush has smaller-appearing bill, is more contrastingly marked above. In flight, Russet-tailed shows white in tail corners, absent in Bassian. The smaller wingbar has more prominent pale tips in adult Russet-tailed than Bassian. Introduced Song Thrush has spots rather than scaly marks below. Inhabits wet forests, where it forages in leaf litter. Song a distinctive, thin “whee-doo,” falling in pitch, very unlike Bassian.
