About the Grasshopper Warbler

The common grasshopper warbler or just grasshopper warbler (Locustella naevia) is a species of Old World warbler in the genus Locustella. It breeds across much of temperate Europe and the western Palearctic. It is migratory, wintering across northern tropical Africa just south of the Sahara, and also locally in India.

This small passerine bird is found in dense grassland vegetation, often close to water, and usually with a few small scattered shrubs. It is a medium-sized warbler about 13 cm (5 in) long. The adult has a streaked brown back and whitish grey underparts which are unstreaked except on the undertail coverts. The sexes are identical, as with most warblers, but young birds are yellower below. Like most warblers, it is insectivorous. Four to seven eggs are laid in a nest on or near the ground in thick vegetation or in a tussock of grass.

This is a species which skulks in the undergrowth, creeping through bushes and low foliage, and which is very difficult to see except when singing from a prominent position. The song, which gives this species its name, is a mechanical grasshopper-like reeling, often given at dawn or dusk.
