Roraiman Antbird (Myrmelastes saturatus)


Taxonomy

French: Alapi des tépuis German: Schieferameisenvogel Spanish: Hormiguero del Roraima
Taxonomy:

Heterocnemis saturata

Salvin

, 1885,

Mt Roraima, 3500 feet [c. 1065 m]

.

See M. schistaceus (below). Until recently considered conspecific with M. leucostigma (along with M. rufifacies, M. brunneiceps and M. humaythae), but analysis separates it in a clade with M. schistaceus#R. Differs from M. leucostigma in its much higher-pitched (3) and slower-paced song (1); darker plumage in both sexes with female chestnut vs bright ferruginous below (1); male with virtually all-black vs three-quarters grey lower mandible (1); male with shorter wing (from published data#R at least 1); moreover, distribution parapatric (3). Position as geographical outlier to other taxa here accepted as reducing need for further comparisons, except in the case of M. brunneiceps, which superficially sings rather similarly (see under that species). Two subspecies recognized.

    Status and conservation

    Not globally threatened (Least Concern). Uncommon throughout most of its range, and only recently (1998) discovered in Guyana. Known from several protected areas across the... read more
