Locustella luscinoides

Savi's Warbler, Locustella luscinoides, is an Old World warbler in the grass warbler genus Locustella. It breeds in southern Europe into temperate western Asia. It is migratory, wintering in sub-Saharan Africa.

This small passerine bird is a species found in reed beds, usually with some bushes. 3-6 eggs are laid in a nest in reeds. This species is only a rare breeder in southern England.

This is a medium-sized warbler. The adult has a unstreaked grey-brown back, whitish grey underparts and a concolourous undertail, which is a distinction from River Warbler. The sexes are identical, as with most warblers, but young birds are yellower below. Like most warblers, it is insectivorous.

This is not a skulky species, but can be difficult to see in the reeds except sometimes when singing.

The song is a monotonous mechanical insect-like reeling, often given at dusk. It is similar to the song of a Grasshopper Warbler, but is faster and deeper, like a mole-cricket.

This bird is named after the Italian ornithologist Paolo Savi.
