Slaty Gnateater (Conopophaga ardesiaca) - HBW 8, p. 746

French: Conophage ardoisé German: Olivgrauer Mückenfresser Spanish: Jejenero Pizarroso

Taxonomy: Conopophaga ardesiaca d’Orbigny and Lafresnaye, 1837, Yungas, Bolivia.
Apparently closely allied to C. peruviana and C. castaneiceps and part of the C. lineata lineage, which is also thought to include C. roberti and, perhaps, C. melanogaster. Range limits of races, and especially whether they meet, are not known. Meets C. castaneiceps brunneinucha in SE Cuzco, which probably marks N limit of range. Plumage variation within Bolivian part of range confusing, with seemingly both dark and light specimens from Cochabamba, and three geographically defined types of back colour in females; of these, the olivaceous form, with tw..

Taxonomy: Conopophaga ardesiaca d’Orbigny and Lafresnaye, 1837, Yungas, Bolivia.
Apparently closely allied to C. peruviana and C. castaneiceps and part of the C. lineata lineage, which is also thought to include C. roberti and, perhaps, C. melanogaster. Range limits of races, and especially whether they meet, are not known. Meets C. castaneiceps brunneinucha in SE Cuzco, which probably marks N limit of range. Plumage variation within Bolivian part of range confusing, with seemingly both dark and light specimens from Cochabamba, and three geographically defined types of back colour in females; of these, the olivaceous form, with two specimens from semi-humid forest of Santa Cruz, may represent another, as yet undescribed taxon. Further research and, probably, taxonomic revision required. Two subspecies currently recognized.

Subspecies and Distribution:

  • saturata Berlepsch & Stolzmann, 1906 - E Andes of S Peru S from SE Cuzco (in Marcapata Valley).
  • ardesiaca d’Orbigny & Lafresnaye, 1837 - from SE Peru (probably from Puno) S to S Bolivia (Tarija).
