The northern cardinal (Cardinalis cardinalis) is a bird in the genus Cardinalis. It can be found in southeastern Canada, the United States, Mexico, Belize, and Guatemala, and as an introduced species in a few locations such as Bermuda and Hawaii. Its habitat includes woodlands, gardens, shrublands, and wetlands. The northern cardinal is a mid-sized perching songbird with a body length of 21โ23 cm (8.3โ9.1 in) and a crest on the top of the head. It is mainly granivorous, but also feeds on insects and fruit. The male behaves territorially, marking out his territory with song. During courtship, the male feeds seed to the female beak-to-beak. A clutch of three to four eggs is laid, and two to four clutches are produced each year. These photos of a male and female northern cardinal, which show their sexual dimorphism, were photographed in Central Park, New York City, United States.Photograph credit: Rhododendrites
