Pallas's grasshopper warbler, also known as the rusty-rumped warbler, is an Old World warbler. The adult has a streaked brown back and whitish-grey underparts unstreaked except on the undertail, and the sexes are identical, young birds being yellower below. The white tips on the tail give it the nickname 'PG Tips' (Wikipedia, general species account).
It breeds in the eastern Palearctic, from the Altai Mountains, Mongolia and Transbaikalia to north-eastern China, the Korean Peninsula and the islands in the Sea of Okhotsk. It is migratory, wintering from India eastward to Indonesia. Four to seven eggs are laid in a nest on the ground in grass (Wikipedia, general species account).
