Rufous-breasted Antpitta (Grallaricula leymebambae)


Taxonomy

Hitherto treated as conspecific with G. ferrugineipectus, although long known to be vocally distinct; differs in its larger size (effect size for wing 4.0, score 2); darker (olive-grey vs greyish-ochre) upperparts (1); darker (olive-grey) on preocular ring, ear-coverts and malar (last creating pale submoustachial line) and as mottling on breast (2); orange-rust of flank sides extending onto vent (1); higher-pitched (3) and faster-paced (2) song. Online recordings indicate a population in Ecuador with a degree of vocal difference, suggesting probably a new taxon; and Bolivian birds are slightly darker, although differences perhaps clinal. Monotypic.

Distribution:

Pacific slope in extreme S Ecuador (S Loja)#R, NW Peru (Piura, NE Lambayeque#R) and from S Amazonas (S & E of R Marañón) S to W Bolivia (La Paz); recorded also, perhaps this taxon, in N Ecuador (Pichincha)#R.

Descriptive notes

10–10·5 cm; male 15–21 g, female 13–18 g. Compared to formerly conspecific G. ferrugineipectus is larger and darker, more olivaceous above, darker and buffier (less... read more

Contents of c. 40 stomachs were beetles and other insects. Usually in pairs. Hops along moss-covered branches, drops briefly to forest... read more

Breeding

Virtually nothing known; birds of both sexes collected in N Bolivia in late Jul and early Aug showed no signs of breeding.

Movements

Presumably sedentary.

Status and conservation

Not globally threatened (Least Concern). Comparatively large range and population believed to be broadly stable. Only recently discovered in extreme S Ecuador. Apparently... read more
