Northern Cardinal (Male)

The Northern Cardinal (Cardinalis cardinalis) is a North American bird in the genus Cardinalis; it is also known colloquially as the Redbird or Common Cardinal. It can be found in southern Canada, through the eastern United States from Maine to Texas and south through Mexico. It is found in woodlands, gardens, shrublands, and swamps.
The Northern Cardinal is a mid-sized songbird with a body length of 21–23 cm (8.3–9.1 in). It has a distinctive crest on the head and a mask on the face which is black in the male and gray in the female. The male is a vibrant red, while the female is a dull reddish olive. The northern cardinal 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. It was once prized as a pet, but its sale as a cage bird was banned in the United States by the Migratory Bird Treaty Act of 1918. [Wikipedia]

Northern Cardinal (Female)

The male Northern Cardinal is perhaps responsible for getting more people to open up a field guide than any other bird. They’re a perfect combination of familiarity, conspicuousness, and style: a shade of red you can’t take your eyes off. Even the brown females sport a sharp crest and warm red accents. Cardinals don’t migrate, and they don’t molt into a dull plumage, so they’re still breathtaking in winter’s snowy backyards. In summer, their sweet whistles are one of the first sounds of the morning. [All About Birds]

Northern Cardinal Facts [All About Birds]

• Only a few female North American songbirds sing, but the female Northern Cardinal does, and often while sitting on the nest. This may give the male information about when to bring food to the nest. A mated pair shares song phrases, but the female may sing a longer and slightly more complex song than the male.

• Many people are perplexed each spring by the sight of a cardinal attacking its reflection in a window, car mirror, or shiny bumper. Both males and females do this, and most often in spring and early summer when they are obsessed with defending their territory against any intruders. Birds may spend hours fighting these intruders without giving up. A few weeks later, as levels of aggressive hormones subside, these attacks should end (though one female kept up this behavior every day or so for six months without stopping).

• The male cardinal fiercely defends its breeding territory from other males. When a male sees its reflection in glass surfaces, it frequently will spend hours fighting the imaginary intruder.

• The oldest recorded Northern Cardinal was a female and was 15 years, 9 months old when she was found in Pennsylvania.
