Why Birds Are Red
Red plumage in birds comes from carotenoid pigments obtained through diet. Males with the brightest red tend to be the healthiest and best-fed, making colour an honest signal of quality to potential mates. Species like the Northern Cardinal and House Finch can vary in intensity from pale orange to deep red depending on food availability.
The Northern Cardinal is the most widespread and recognisable red bird in North America, found in every eastern state year-round. West of the Great Plains, House Finches take over as the most common red bird in backyards and towns.
