(Description from Wikipedia, the free encyclopedia)
The Cardinals or Cardinalidae are a family of passerine birds found in North and South America. The South American cardinals in the genus Paroaria are placed in another family, the Thraupidae (previously placed in Emberizidae).
These are robust, seed-eating birds, with strong bills. The average size is about 12-cm, 11.5-gram. They are typically associated with open woodlands. The sexes usually have distinctive appearances; the family is named for the red plumage whose color resembles that of a Catholic cardinal's vestments.
The "buntings" or groups, in this family are sometimes generically known as "tropical buntings" (though not all live in the tropics) or "North American buntings" (though there are other buntings in North America) to distinguish them from the true buntings. Likewise the grosbeaks in this family are sometimes called "cardinal-grosbeaks" to distinguish them from other grosbeaks. The name "cardinal-grosbeak" can also apply to this family as a whole.
