Find a slope in Vilnius and you may find breeding Greenish Warbler. They tend to avoid flat areas. Despite its rarity in the UK, as a species it is fairly widespread, being found in north-eastern Europe and temperate to subtropical Asia. They are strongly migratory, wintering in India. Greenish Warblers provide plenty of head scratching moments for ornithologists as they are part of a highly confusing ring species triangle involving two other similar looking warblers, namely; Green and Two-barred (Green). To confound the issue even further, there’s an array of different subspecies. So, good luck when confronted with one of these birds in an unexpected place!
