Tanagers (Thraupidae)

Pearly-breasted Conebill (Conirostrum margaritae) - HBW 16, p. 262

French: Conirostre marguerite German: Perlbrust-Spitzschnabel Spanish: Conirrostro Pechigrís

Taxonomy: Ateleodacnis margaritae Holt, 1931, north bank of Amazon at Ceo de Arary, above Parintins, Amazonas, Brazil.
Genus has sometimes been placed in Coerebidae or Parulidae, but molecular-genetic data indicate that it belongs in present family, with Oreomanes as sister-group. This species was originally placed in genus Ateleodacnis, and some taxonomists argue that it, along with the other lowland conebills (C. speciosum, C. leucogenys and C. bicolor), should be returned to that genus; as a group they are morphologically quite distinct from most highland members of present genus. Monotypic.

Distribution: NE Peru on banks of lower R Napo (sightings to 50 km or more above mouth) and banks of R Amazon (vicinity of Iquitos), E in Brazil to vicinity of R Jamunda (R Nhamundá); isolated record near junction of R Beni and R Iténez (in Brazil known as R Guaporé), Bolivia.
