Tyrant-flycatchers (Tyrannidae)

White-crested Elaenia (Elaenia albiceps) - HBW 9, p. 268

French: Élénie à cimier blanc German: Weißbauch-Olivtyrann Spanish: Fiofío Crestiblanco
Other common names: Peruvian Elaenia (modesta); Chilean Elaenia (chilensis)

Taxonomy: M[uscipeta] albiceps d’Orbigny and Lafresnaye, 1837, Yungas, Bolivia.
Closely related to E. parvirostris, and vocally very similar; has been suggested that the two are conspecific, but they apparently do not hybridize across broad area of range overlap in Argentina. Race chilensis has been treated as a separate species, although no significant vocal differences from others; this race hybridizes locally with E. parvirostris where ranges overlap in S Bolivia (but not in NW Argentina). In addition, race modesta sometimes treated as a separate species. Race griseigularis possibly hybridizes with E. pallatangae in Ecuador. S.. View all taxonomy...
