Dotterels are summer visitors to Scotland, so this bird has probably stopped off on migration and is a rare and unusual bird sighting in Berkshire. The RSPB website shows the bird as a passage migrant in Norfolk, so this is quite a way off its regular territory. The Dotterel is a Blackbird sized bird which has an orange breast and black and white horizontal markings, together with a striking grey and black upper body and head. The UK population is only 500-700 birds, so Dotterels are a notable rarity.
