Paddyfield Warbler

The paddyfield warbler is a marsh warbler 13 cm long with a wingspan of 15–17.5 cm, close in size to the Eurasian reed warbler but with a shorter bill and wingspan. The adult has an unstreaked pale brown back, buff underparts and a warm brown rump, with a clearer whitish eyebrow and a short pointed bill; young birds are richer buff below. It breeds in the temperate central Palearctic and is a rare vagrant to western Europe, with small breeding populations on the Black Sea shores of Bulgaria and Romania (Wikipedia, general species account).

Four or five eggs are laid in a nest in grass. The song is fast, like the marsh warbler's, with much mimicry and typical acrocephaline whistles, though weaker and more rhythmic (Wikipedia, general species account).
