Olive-tree Warbler
Hippolais olivetorum (Strickland, 1837)
OLTWA 
12580
Family: Passeriformes > Acrocephalidae
Olive-tree Warbler is a large, elongated warbler with a long bill, and is an extremely rare visitor to Britain.
This species was added to the British List on the basis of an individual seen and photographed on Shetland in 2006, where it had initially been thought to be either and Icterine Warbler or Eastern Olivaceous Warbler.
The relatively restricted breeding range extends from Croatia south to Greece, and east to the Black Sea and central Turkey. The breeding range appears to be restricted to sites that are fairly close to the sea.
