Eurasian Golden Oriole

The Eurasian golden oriole is a medium-sized passerine, approximately twenty-four centimetres long with a forty-four to forty-five centimetre wingspan. Adult males are unmistakably bright yellow and black, whereas females are much duller and greener. Despite the male's colour, the species can be difficult to see among sunlit canopy leaves. In flight it recalls a thrush, moving strongly and directly with shallow dips. Its fluting song often gives away a hidden bird, while the call is much harsher. (Wikipedia, general species account)

This is the only Old World oriole that breeds through the temperate Northern Hemisphere. Its breeding range stretches from western Europe and Scandinavia eastward across the Palearctic to China, while winter is spent in central and southern Africa. The species is therefore a summer migrant across most of its breeding distribution. Linnaeus originally described it in 1758 as Coracias oriolus, placing it with the rollers; it was later transferred to Oriolus, the genus Linnaeus introduced in 1766.
