Oriolus



Orioles are colourful Old World passerine birds in the genus Oriolus, the namesake of the corvoidean family Oriolidae. They are not related to the New World orioles, which are icterids (family Icteridae) and, belonging to the superfamily Passeroidea songbirds, are quite unrelated to the true orioles.

The orioles are a mainly tropical group, although one species (Eurasian Golden Oriole, O. oriolus) breeds in temperate regions.

Isolated species An unidentified oriole was heard on May 14, 1994, at 1,000 meters ASL south of the summit of Camiguin in the Philippines, where the genus was not previously known to occur. It might have been an undescribed taxon, or simply a vagrant of a known species.
