Comoro Thrush (Turdus bewsheri)


French: Merle des Comores German: Komorendrossel Spanish: Zorzal de las Comoras

Turdus bewsheri

E. Newton

, 1877,

Anjouan, Comoro Islands


Genetic data#R#R indicate sister relationship to T. libonyana. Nominate race has been proposed as a separate species on grounds of song, which differs from that of comorensis, but moheliensis apparently intermediate between the two. Unpublished biomolecular studies of all three taxa tend to support a three-way split, although only nominate shows significant morphological differences. Further study needed. Three subspecies recognized.
