Family Mockingbirds and Thrashers (Mimidae)


White-breasted Thrasher (Ramphocinclus brachyurus)


French: Moqueur gorge-blanche German: Weißbrust-Spottdrossel Spanish: Cuitlacoche pechiblanco

Turdus brachyurus


, 1818,

Martinique, Lesser Antilles


In the past sometimes placed in genus Cinclocerthia. Race sanctaeluciae considered a separate species by some authors and evidence highly supportive: differs in the browner shade of its grey-brown plumage (1); blacker lores and ear-coverts (1); purer white underparts (1); more neatly organized (less irregular) flank markings (ns[1]); lack of scalloping on wing-coverts (ns[1]); anecdotally somewhat different calls (no recordings available; allow 1); mildly different ecology (nests reportedly placed much lower in vegetation; clearer evidence needed) (ns[1]); and larger size (effect size for male tail 5.71, but n=7 vs n=6; precautionarily allowed 2). Two subspecies recognized.
