Other common names: Giant Elaenia; Duida Elaenia (tyleri)

Taxonomy: Elaenia dayi Chapman, 1929, Cerro Roraima, 8600 feet [c. 2620 m], Venezuela.
Apparently most closely related to E. obscura on basis of wing shape and plumage pattern; may be part of superspecies formed by that species and E. frantzii. Three subspecies recognized.

Subspecies and Distribution:

  • tyleri Chapman, 1929 - mountains of SC Venezuela in Amazonas (cerros Parú, Huachamacari, Marahuaca, Duida) and SW Bolívar (Meseta de Jaua).
  • auyantepui J. T. Zimmer & Phelps, Sr, 1952 - Auyán-tepui, in SE Bolívar.
  • dayi Chapman, 1929 - mountains and Gran Sabana of SE Venezuela (cerros Ptari-tepui, Chimantá-tepui, Kukenam, Roraima); probably also in adjacent Guyana.
