American Robin

Identification

The American robin is a medium-sized thrush with distinctive plumage that makes it readily recognisable across North America. Males are characterised by a brick-red to orange breast and underparts, contrasting with a dark grey-brown back and blackish head. Females are generally duller, with paler underparts and a lighter head. The species takes its common name from this reddish-orange breast, which early colonists thought resembled the European robin, though the two birds are not closely related and belong to different families.

Seven subspecies are recognised, showing subtle but consistent variations across the continent. Eastern populations (T. m. nigrideus and T. m. migratorius) are typically darker-headed with richer red underparts, while western birds (T. m. caurinus and T. m. propinquus) tend to be paler and more brownish-grey. The southwestern Mexican subspecies (T. m. phillipsi) is slightly smaller with a rustier tone to the male's underparts. Some western females may show almost no red below, requiring attention to head and back patterns for confident identification.
