Icterids make up a family (Icteridae) of small to medium-sized, often colorful passerine birds restricted to the New World. Most species have black as a predominant plumage color, often enlivened by yellow, orange or red. The family is extremely varied in size, shape, behavior and coloration. The name, meaning "jaundiced ones" (from the prominent yellow feathers of many species) comes from the Ancient Greek ikteros, through the Latin ictericus. This group includes the New World blackbirds, New World orioles, the bobolink, meadowlarks, grackles, cowbirds, oropendolas and caciques.
