The eastern olivaceous warbler (Iduna pallida) is a "warbler", formerly placed in the Old World warblers when these were a paraphyletic wastebin taxon. It is now considered a member of the acrocephaline warblers, Acrocephalidae, in the tree warbler genus Iduna. It was formerly regarded as part of a wider "olivaceous warbler" species, but as a result of modern taxonomic developments, this species is now usually considered distinct from the western olivaceous warbler, Iduna opaca. Order: Passeriformes, Family: Acrocephalidae, Genus: Iduna, Species: Iduna pallida (Hemprich & Ehrenberg, 1833), Synonyms: Hippolais pallida (Ehrenberg, 1833).
