A very popular bird here in the eastern United States is the Northern Cardinal. So popular, it is the state bird of seven states. They are found as far north as Canada, and to Central America in the south. At one time, they were captured and kept as caged birds, but it is no longer legal to do so. The Northern Cardinal measures 23 cm (or 8.3 inches). Pairs mate for life. The male is bright red, the female a reddish brown with red highlights on the crest, wings, and tail.
