Eastern Olivaceous Warbler
The Eastern Olivaceous Warbler is a species of marsh warbler in the genus Acrocephalus. It was formerly regarded as part of a wider "Olivaceous Warbler" species but as a result of modern taxonomic developments, it is now usually considered distinct from the Western Olivaceous Warbler.
The Eastern Olivaceous Warbler is a medium-sized warbler broadly similar in appearance to the Reed Warbler. The adult has a plain pale brown back and whitish underparts. The bill is strong and pointed and the legs are grey. The plumage of the sexes is identical. It has a characteristic downward tail flick and the song is a fast nasal babbling. The Western Olivaceous Warbler differs from the Eastern Olivaceous Warbler in being larger and having a browner tinge to the upperparts.
The Eastern Olivaceous Warbler breeds in dry open country with bushes or trees in south east Europe and the Middle East and a sub-species is thought to be locally common as a breeding species in south east Morocco. It is migratory and winters in sub-Saharan Africa or Arabia. It is a rare vagrant to north Europe.
Like most warblers, the Eastern Olivaceous Warbler is insectivorous.
