Savi's Warbler

Locustella luscinioides (Savi, 1824) VI SAVWA 12380
Family: Passeriformes > Locustellidae

What it lacks in colour, the reedbed-loving plain brown Savi’s Warbler makes up for with its loud insect-like buzzing song.

The Savi’s Warbler is a very rare breeding bird in the UK, largely confined to a discrete number of reedbed sites in East Anglia and southern England. It is a summer visitor from trans-Saharan Africa and can be heard singing by a lucky few between May and August.

An estimated five to 10 pairs of Savi's Warbler breed in the UK. Savi’s Warblers can be found when on migration but even at this time, despite the European breeding population estimate of around on million pairs, the species is still very rare here.
