About Cardinal

The northern cardinal is so well loved that it has been named the official bird of no fewer than seven U.S. states. Bright red cardinals are easily identified by even casual bird watchers, and are often seen frequenting backyards and bird feeders. When foraging elsewhere the birds eat insects, seeds, grain, fruit, and sap.

Males can be aggressive when defending their territory, and they frequently attack other males who intrude. This tendency sometimes leads cardinals to fly into glass windows, when they charge an "intruding bird" that is really their own reflection.
