Thrushes (Turdidae)

White-throated Thrush (Turdus albicollis) - HBW 10, p. 663

French: Merle à col blanc German: Trauerdrossel Spanish: Zorzal Cuelliblanco
Other common names: White-necked/White-collared Thrush, White-necked Robin (“nominate group”); Dagua Thrush (daguae); Grey-flanked Thrush (phaeopygos); Paraguayan Thrush (paraguayensis); Rufous-flanked Thrush (nominate); White-necked Thrush (crotopezus)

Taxonomy: Turdus albicollis Vieillot, 1818, Rio de Janeiro, Brazil.
Races form two groups, the “assimilis group” of Middle America and the “nominate group” of South America, commonly treated as two separate species. In addition, race daguae recently considered possibly a separate species, and the three races in extreme SE of range (nominate, paraguayensis, crotopezus) have been proposed as representing a further species on basis of minor differences. In all cases, however, evidence for such splitting has not been coherently marshalled, and in some instances involves largely subjective vocal assessments. Moreover, some races..

Taxonomy: Turdus albicollis Vieillot, 1818, Rio de Janeiro, Brazil.
Races form two groups, the “assimilis group” of Middle America and the “nominate group” of South America, commonly treated as two separate species. In addition, race daguae recently considered possibly a separate species, and the three races in extreme SE of range (nominate, paraguayensis, crotopezus) have been proposed as representing a further species on basis of minor differences. In all cases, however, evidence for such splitting has not been coherently marshalled, and in some instances involves largely subjective vocal assessments. Moreover, some races very weakly differentiated and possibly untenable. Proposed race oblitus (from Costa Rica) merged with leucauchen. Twenty-one subspecies currently recognized.
