This small passerine bird is a species found in open-canopy oakwoods, olive groves, orchards and almond plantations. Three or four eggs are laid in a nest in a low tree or a bush.

This is a medium-sized warbler, similar to in size to the barred warbler, with a slightly longer bill and shorter tail. It is the largest Hippolais warbler, with a heavy bill, rather flat crown, long wings, and heavy legs. The adult has a dusty- or brownish-grey back and wings, and dusty-white underparts.

The genus name Hippolais is from Ancient Greek hupolais, as misspelt by Linnaeus. It referred to a small bird mentioned by Aristotle and others and may be onomatopoeic or derived from hupo,"under", and laas, "stone". The specific olivetorum is Latin for "of the olive groves ".[2]
