- Sylvia nisoria
Identification
15 cm. Grey uppeparts, grey and white barring on underparts of adults, pale edges to wing feathers which creates a double wing bar. Juvenile and first winter birds may show no barring at all.
Distribution
Main breeding range is from eastern Germany, the Czech Republic and eastern Austria south-east to Bulgaria and east to the foothills of the Urals, the Caspian and Caucasus. Also breeds in scattered pockets in southern Sweden (mainly coastal areas and Oland and Gotland), and the south coast of Finland, in southern Switzerland and northern Italy, throughout the Balkans and possibly also Turkey. Probably now extinct as a breeding species in Denmark.
Leaves breeding areas in August-September to winter in East Africa, travelling via the eastern Mediterranean. Return movement takes place in mid-late May. Passage birds occur throughout east and Southeast Europe and the Middle East and occurs as a rare migrant as far west as Britain. Around 100-150, mainly 1st-winter birds, occur per year in Britain chiefly in the Northern Isles, on the east and south coasts and on Scilly. Most occur in August-October, very rare in spring.
Vagrant to Iceland, France, Belgium, Spain, Sardinia and Malta.
