|Male northern cardinal|
The South American cardinals in the genus Paroaria are placed in the tanager family Thraupidae. Contrariwise, DNA analysis of the genera Piranga (which includes the scarlet tanager, summer tanager, and western tanager), Chlorothraupis, and Habia showed their closer relationship to the cardinal family. They have been reassigned to that family by the American Ornithological Society.

They are robust, seed-eating birds with strong bills. The family's smallest member is the 12-cm (4.7-in), 11.5-g (0.40-oz) orange-breasted bunting. They are typically associated with open woodland. The sexes usually have distinctive appearances. The northern cardinal type species was named by colonists for the male's red crest, reminiscent of a Catholic cardinal's biretta.
The "North American buntings" are known as such to distinguish them from buntings of the Old World family Emberizidae. The name "cardinal-grosbeak" can also apply to the cardinalid family as a whole.
Biological suppression of West Nile virus
A study conducted in 2016 in Atlanta, Georgia, on West Nile virus transmission in the United States, found that unlike other species, cardinals biologically suppress the disease upon infection.
