S. F. Baird, 1864,
Todos Santos, Cape San Lucas, Baja California.
Previously considered conspecific with T. migratorius, but differs in its pale buff vs rufous breast to lower belly (3); mid-grey vs blackish-grey crown, head sides and throat streaks (2); complete vs partial white supercilium (2); somewhat longer bill (effect size 2.86, score 2); and marginally shorter tarsus (based on published evidence#R possibly 1); song “burrier and less strident”#R, but at least some T. migratorius from Mexican mainland sound burrier than those farther N (ns), hence more vocal data needed. Monotypic.
Sierra de la Laguna, in extreme S Baja California (W Mexico).
