The family Cardinalidae is a group of small to medium-sized passerine birds commonly known as cardinals, grosbeaks, and some buntings. These birds are primarily found in North and South America, inhabiting woodlands, shrublands, and gardens. Members of this family are often sexually dimorphic, with males displaying bright, vibrant plumage—such as the well-known red of the Northern Cardinal—while females tend to be more subdued in color. Cardinalidae species are seed-eaters with strong, conical bills, though they may also consume insects and fruits. They are generally monogamous, with many species exhibiting territorial behavior and complex vocalizations, making them a familiar and popular group among birdwatchers.
