About the Eastern Olivaceous Warbler

The eastern olivaceous warbler (Iduna pallida), known simply as the olivaceous warbler when its western relative is referred to as the 'isabelline warbler', is a small passerine bird with drab plumage tones, that is native to the Old World. For the most part it breeds in southeastern Europe, the Middle East and adjacent western Asia, and winters in the northern Afrotropics.

The eastern olivaceous warbler 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.

Keyserling and Blasius gave no explanation of the genus name Iduna. The specific pallida is Latin for "pale". This small passerine bird is found in dry open country, including cultivation, with bushes or some trees. Like most warblers it is insectivorous.

It is migratory, wintering in sub-Saharan Africa... Wikipedia →
