confinis
L. confinis  similar, nearly related.
● "Upon the whole, it may be that the specimen before me represents an abnormal plumage of T. migratorius; but its rather different proportions, much paler ground color beneath, greater extent of white on the belly, absence of black or dusky on the head, etc., leads me to consider it as distinct" (S. Baird 1864) (Turdus).
