Golden Oriole

  • Golden Oriole Classification and Evolution

The Golden Oriole (also known as the Eurasian Oriole), is a small species of Bird found throughout Europe and western Asia. The Golden Oriole's name is thought to have arisen during the 18th century after the classical Latin word meaning gold. Although almost indistinguishable in appearance, some believe that the Golden Orioles found in Europe, are actually a separate sub-species to those found in Asia. They are also known to be the only member of the Oriole family that breeds in the more temperate regions of the northern hemisphere.
  • Golden Oriole Anatomy and Appearance

The male Golden Oriole is an incredibly coloured Bird, with striking yellow and jet black plumage, and fully black wings. As with many other Birds, the female of the species is more dull-looking being slightly greener in colour. Both however, are hard to spot in the canopy as they are perfectly camouflaged amongst the leaves. Golden Orioles tend to be between 20 - 24 cm in height and are often mistaken for Thrushes and even green Woodpeckers when in flight. They have dark red eyes, and a fairly thick, pink beak that is curved slightly downwards at the end.

  • Golden Oriole Distribution and Habitat

The Golden Oriole is predominantly found throughout Europe and western Asia but also in parts of Africa. The Golden Oriole is a summer migrant meaning that it migrates north for the cooler summer climates, and flies back south to the tropics when the winter begins to emerge. The Golden Oriole is nearly always found in well-timbered forests and woodland, along with parks, orchards and gardens. They spend the majority of their time high in the tree canopy where their distinctive plumage helps them to remain hidden from lurking predators.
  • Golden Oriole Behaviour and Lifestyle

Due to it's excellent camouflage amongst the leaves, and it's shy nature, the Golden Oriole is an almost impossible Bird to spot. However, it is it's unmistakable song that alerts all around to it's presence, which is said to sound very fluty and can be heard over considerable distances. Their basic calls however are often compared to the screech of a Jay, but both are used to communicate with other Golden Orioles inhabiting the surrounding forest. The Golden Oriole is a migratory and generally quite solitary Bird, but can be seen migrating, often under the cover of night, in large flocks.
  • Golden Oriole Reproduction and Life Cycles

The Golden Oriole breeds in the more temperate northern regions during the summer months, where courtship displays involve them chasing one another from tree to tree and through the canopy. The female Golden Oriole builds her nest, generally in the fork of a tree out of plant fibres and stems, in the shape of a shallow cup. She lays between 3 and 6 eggs which hatch after an incubation period of between 15 and 18 days, that is predominantly conducted by the female. Once hatched, both Golden Oriole parents help to feed and look after their young, which will have left their nest (fledged) within 20 days. Golden Orioles usually live to be around 9 or 10 years old.
