Tyrant-flycatchers (Tyrannidae)

Small-billed Elaenia (Elaenia parvirostris) - HBW 9, p. 269

French: Élénie à bec court German: Dreibinden-Olivtyrann Spanish: Fiofío Piquicorto

Taxonomy: Elainea [sic] parvirostris Pelzeln, 1868, Curitiba, Paraná, Brazil.
Described taxon E. aenigma is a synonym of present species. Closely related to E. albiceps, and vocalizations are very similar; these two forms have been suggested as perhaps being conspecific, but apparently do not hybridize across a broad area of range overlap in Argentina, although hybridization does occur in a narrow area of overlap in S Bolivia. Reported hybridization between present species and E. mesoleuca in SE Brazil (Rio Grande do Sul) is disputed by some authors. Monotypic.

Distribution: Breeds E & SE Bolivia, Paraguay, S Brazil (São Paulo S to Rio Grande do Sul), NE Argentina (S to Buenos Aires) and Uruguay. Migrates N to Amazon Basin and as far as NE Colombia, N Venezuela, Netherlands Antilles, Trinidad and the Guianas.
