|maybe they're Virginia Redbirds?|
We all know what a Cardinal is...or do we?? The Texas Ornithological Society, and most birdwatchers, know it as a Northern Cardinal. But many people (understandably) call it a Redbird (forgetting about the females and juveniles). In Virginia it's a Virginia Redbird or Virginia Nightingale. A few birders call it a Cardinal Redbird. They're all right in a way! Many years ago John James Audubon even knew it as a Cardinal Grosbeak. The only universally-correct name is the cumbersome Latin name Cardinalis cardinalis, but that sounds snobbish.
Those are the facts! I'm not worried, but if I were a rabbit or housecat I would be.
