Moltoni's Warbler

Curruca subalpina

Introduction

A small warbler with blue-grey upper-parts and pink underparts, this species was split from the Subalpine Warbler complex. It is a scarce visitor that breeds in northern Italy and on several Mediterranean islands.

The first British record, confirmed by plumage and genetic analysis, was shot on St Kilda in 1894 and is in the collection of the Natural History Museum at Tring.
