Orioles are small birds part of the Icteridae family, commonly referred to as New World Orioles. The birds of the Old World, going by the name Old World orioles, aren’t similar, belonging to a different family altogether, the Oriolidae family. Yet, the two closely resemble each other in size, diet, plumage, and behavior. They thus form a perfect example of convergent evolution, unrelated to each other yet bearing similar traits.

Interesting Facts
Icterus, a prominent genus of the Icterid family to which the New World orioles belong, has been derived from a Latin word translating to jaundice. The sight of this bird was possibly helpful in treating jaundice. The bird in question was the Eurasian golden oriole. Mathurin Jacques Brisson, who coined this term, used Icterus to refer to New world birds.
