Pallas's grasshopper warbler (Helopsaltes certhiola), also known as the rusty-rumped warbler, is an

Palearctic: from the Altai Mountains, Mongolia and Transbaikalia to northeastern China, the Korean Peninsula, and islands in the Sea of Okhotsk (Sakhalin and Kuril Islands). It is migratory, wintering from India eastward to Indonesia. It is a rare migrant in Sri Lanka
.

Habitat

This small

Shetland
; for a species that only rarely appears in western Europe, it can be found there with some regularity.

Description

In Kolkata, West Bengal, India.

This is a medium-sized warbler. The adult has a streaked brown back, whitish grey underparts, unstreaked except on the undertail. The sexes are identical, as with most warblers, but young birds are yellower below. Like most warblers, it is insectivorous. It is very similar to the

colloquial, mnemonic name of "PG Tips
".

This is a skulking species which is very difficult to see except sometimes when singing. It creeps through grass and low foliage.

Voice

The song is not the mechanical insect-like reeling produced by the common grasshopper warbler and some other Locustella warblers, but an inventive Acrocephalus-like melody.
