HI jamie et al.:
This plumage variation is not unheard of in Varied but is extremely rare:
1) Specimen at California State University.
2) the one European record (Cornwall Britain: 14-23 Nov. 1982)is of this
"morph".
See THRUSHES by Peter Clement page 237 and plate 13 and also

Mitchell and Steve Young (pages116-17).
