A collective noun for a group of cardinals is a “college,” “radiance,” or “cardinality.” While these terms are recognized, they are not frequently used in common birdwatching or ornithological contexts. The more common and generally accepted practice is to simply refer to them as a group of cardinals.
Understanding collective nouns, though not essential for basic bird identification, adds a layer of appreciation for the richness of language and the natural world. Historically, collective nouns often reflected perceived characteristics of the animals they described. While terms like “college” or “radiance” might evoke the striking plumage of the male cardinal or the wisdom implied by a “college,” their infrequent use underscores a practical approach to describing avian gatherings.
