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.
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. 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.
