Slender-billed Curlew

Slender-billed Curlew

Numenius tenuirostris

Introduction

With no regular breeding, passage or wintering population known, and very few confirmed records globally over recent years, this species is thought likely to have become extinct.

The one British record (Northumberland, 1998) was reviewed by BBRC and BOURC in 2014, who found the identification to be Not Proven, and hence the record is no longer accepted.
