Tyrant-flycatchers (Tyrannidae)

White-eyed Tody-tyrant (Hemitriccus zosterops) - HBW 9, p. 322

French: Todirostre zostérops German: Weißaugen-Todityrann Spanish: Titirijí Ojiblanco

Taxonomy: Euscarthmus Zosterops Pelzeln, 1868, Marabitanas, Rio Negro, Brazil.
Formerly placed in genus Euscarthmornis and, more recently, Idioptilon, both now defunct. Was for long treated as conspecific with H. griseipectus, but the two exhibit major differences in plumage and voice; vocal characters suggest that geographically isolated race naumburgae may belong with that species. E Amazonian populations vocally distinct from those W of R Branco and R Negro, suggesting that two distinct species may be involved; birds from French Guiana described as race rothschildi, and that name (currently synonymized with nominate) would be availa..

Taxonomy: Euscarthmus Zosterops Pelzeln, 1868, Marabitanas, Rio Negro, Brazil.
Formerly placed in genus Euscarthmornis and, more recently, Idioptilon, both now defunct. Was for long treated as conspecific with H. griseipectus, but the two exhibit major differences in plumage and voice; vocal characters suggest that geographically isolated race naumburgae may belong with that species. E Amazonian populations vocally distinct from those W of R Branco and R Negro, suggesting that two distinct species may be involved; birds from French Guiana described as race rothschildi, and that name (currently synonymized with nominate) would be available for E form, if found to be a separate species. Boundary between nominate race and flaviviridis uncertain, as vocal type of former occurs only E of R Branco and R Negro, in N Brazil, and that of latter extends E to those rivers; has been proposed by some authors that the two races be merged. Three subspecies recognized.

Subspecies and Distribution:

  • zosterops (Pelzeln, 1868) - SE Colombia (Caquetá, Vaupés), E Ecuador and NE Peru (Loreto) through S Venezuela (S Amazonas) and much of Brazil N of Amazon (Amazonas, NW Pará, Amapá) to E Surinam and French Guiana.
  • flaviviridis (J. T. Zimmer, 1940) - N Peru (C Amazonas, N San Martín).
  • naumburgae (J. T. Zimmer, 1945) - NE Brazil (Rio Grande do Norte S to Alagoas).
