Subspecies
Catharus minimus (Sibley and Monroe 1990, 1993) has been split into Grey-cheeked Thrush (Catharus minimus) and Bicknell's Thrush (Catharus bicknelli) following AOU (1998).
Formerly placed in Hylocichla, along with Veery (Catharus fuscescens), Bicknell's Thrush (Catharus bicknelli), Swainson's Thrush (Catharus ustulatus) and Hermit Thrush (Catharus guttatus). Until recently treated as conspecific with Bicknell's Thrush (Catharus bicknelli), and vocal, morphological and even biochemical differences very subtle, but seemingly parapatric breeding and probably discrete winter distributions suggest species-level separation just tenable. Nonetheless, intermediates between the two taxa occur, and Newfoundland population of present species approaches Bicknell's Thrush (Catharus bicknelli) in size and coloration. Range of nominate debatable.
The following 2 subspecies are recognised:
aliciae (Baird, SF, 1858) - Extreme north-eastern Siberia, Alaska and Canada. Non-breeding mainly northern South America east of Andes.
minimus (Lafresnaye, 1848) - Eastern Canada (Newfoundland, possibly also northern Quebec). Non-breeding northern South America east of Andes.
