Alternative name: Grasshopper Warbler

Locustella naevia

Identification

A dull brown bird with streaked upperparts and a broad rounded tail which has streaks underneath. A fluffy white throat is often obvious when the bird is singing.

Similar Species

The lack of an eyestripe eliminates Sedge Warbler. Some birds can look remarkably unstreaked and this can often lead to confusion with Savi's Warblers. However, even the most unstreaked Grasshopper Warblers will always have a dark alula.

Distribution

By far the most widespread and common of the Locustella warblers in the Western Palearctic.

Breeds over much of the British Isles (but uncommon) and from northern Spain and western France across Europe north of the Alps to the Black Sea and east to the Urals. In the north occurs in southern Norway and Sweden, the southern half of Finland and Russia to about 61 deg N.

A summer visitor to the Western Palearctic arriving in April-May and departing for wintering grounds in sub-Saharan Africa and India in August-October. Unobtrusive on passage and rarely seen. Occasional winter records from northwest Africa.

Vagrants recorded in Iceland, on Malta and Cyprus, the Middle East, Egypt and on the Cape Verde Islands.

Taxonomy

Subspecies

There are 4 subspecies^[1]:

L. n. naevia:

Europe to eastern Russia and Crimea Peninsula; winters to northern and western Africa

L. n. obscurior: Larger, darker and more boldly marked

Caucasus to Georgia and northern Armenia; winters to north-eastern Africa

L. n. straminea:

Western Siberia to western China (Tien Shan Mountains of western Xinjiang)

L. n. mongolica:

Kazakhstan to Afghanistan and western Mongolia; winters to northern India

Nominate intergrades in the Urals with very similar eastern race straminea, which has been recorded in Britain.

Habitat

Found in wet and dry situations in grasslands and meadows, nettlebeds; reedbeds, cereal fields and often along streams, canals and overgrown ditches.

Behaviour

Movement

Typical flitting warbler flight, but rarely flies during breeding season. Skulks in dense cover.

Vocalisation

Call: a piercing psvitt or chik
Song: a reeling, mechanical suuuur r r r r r

 ==Identification==
-If you are lucky enough to see a Grasshopper Warbler you'll notice that it's a dull brown bird with streaked upperparts and a broad rounded tail which has streaks underneath. A fluffy white throat is often obvious when the bird is singing. The lack of an eyestripe eliminates Sedge Warbler. Some birds can look remarkably unstreaked and this can often lead to confusion with Savi's Warblers. However, even the most unstreaked Grasshopper Warblers will always have a dark alula.
