Century Dictionary and Cyclopedia

1. n. A bird of Europe, Oriolus galbula, so called from its rich yellow color massed with black; also, any bird of the family Oriolidœ. The common Indian oriole is O, kundoo, and many similar birds are found in the Oriental, Ethiopian, and Australian regions.
2. n. Any American hangnest of the family Icteridœ and subfamily lcterinœ, as the Baltimore oriole and orchard-oriole. These birds belong to an entirely different family from orioles properly so called, and indeed to a different series of passerine birds, and they are exclusively American. They are sometimes distinguished as American orioles. The species are numerous, mostly of beautiful yellow or orange and black coloration. See orchard-oriole.
