European stonechat – Saxicola rubicola
is a small passerine bird that was formerly classed as a subspecies of the common stonechat. Long considered a member of the thrush family but now sorted as a flycatcher. The stonechat is 11.5–13 cm long and weighs 13–17 g, slightly smaller than the European robin. Both sexes have distinctively short wings, shorter than those of the more migratory whinchat and Siberian stonechat. The summer male has black upperparts, a black head, an orange throat and breast, and a white belly and vent. It also has a white half-collar on the sides of its neck, a small white scapular patch on the wings, and a very small white patch on the rump often streaked with black. The female has brown upperparts and head, and no white neck patches, rump or belly, these areas being streaked dark brown on paler brown, the only white being the scapular patch on the wings and even this often being buffy-white. Hopefully the pair that was observed in march  (2016) in Stockvike, Gotland will stay there and breed.
