Thrushes (Turdidae)

American Robin (Turdus migratorius) - HBW 10, p. 660

French: Merle d’Amérique German: Wanderdrossel Spanish: Zorzal Robín
Other common names: San Lucas Robin (confinis)

Taxonomy: (Turdus) migratorius Linn aeus, 1766, “in America septentrionali” = North America.
Has in the past been thought to form a superspecies with T. rufitorques on account of behavioural and vocal similarities, but plumages rather different. Highly distinctive race confinis has been treated as a separate species. Geographical variation in rest of range rather clinal. Proposed race aleucus (from Texas) considered indistinguishable from propinquus. Seven subspecies recognized.

Subspecies and Distribution:

  • migratorius Linnaeus, 1766 - Alaska (except SE) and Canada (except SW & E) S to C & NE USA (SW Kansas, Pennsylvania, New Jersey); non-breeding E USA and E Mexico.
