A bird of unmistakable red

The northern cardinal is a medium-sized songbird, famous above all for the male, whose plumage is a bright scarlet red over the whole body, with a small black mask around the beak and throat. On the head stands a showy pointed crest, which the bird can raise and lower. The beak, sturdy and conical, is a vivid orange, suited to cracking seeds. The female is more discreet, with a brownish-olive plumage marked by reddish touches on the wings, tail and crest.

Habitat and distribution

It lives across much of eastern North America, from south-eastern Canada through the eastern United States to Mexico, Belize and Guatemala. It frequents woodlands, gardens, shrublands and wetlands, and has adapted well to suburban environments, so much so that it is a regular guest at garden feeders. It has also been introduced to some locations such as Hawaii and Bermuda.

Song and behaviour

The northern cardinal is a tireless singer: both sexes sing, which is uncommon among birds, with a series of clear, melodious whistles. The song serves to defend the territory and to maintain the pair bond. It is a rather sedentary bird, which does not undertake long migrations, and forms stable pairs that remain together for much of the year.

Feeding

Its diet is based mainly on seeds and grains, which the sturdy beak is perfectly able to open, but it also includes fruit, berries and insects, especially in the breeding season, when the young need protein. At feeders it is particularly attracted to sunflower seeds.

Curiosities and conservation

The northern cardinal is so beloved that it is the emblematic bird of seven states of the United States. It is classified as a species of least concern: its populations are numerous, stable and in some areas even expanding, favoured by the presence of gardens and feeders.

FAQ

Why is the northern cardinal so red?
The male has a bright scarlet plumage over the whole body, which comes from the carotenoid pigments in its food. The vivid colour serves to attract females and to signal its vigour. The female, by contrast, has brown colours with reddish touches that are more camouflaged.
Does the female sing too?
Yes, and it is an unusual trait among birds. Both sexes sing with clear, melodious whistles. The song serves to defend the territory and to maintain the bond between the two partners of the pair, which stays stable for much of the year.
Where does the northern cardinal live?
It lives in eastern North America, from south-eastern Canada through the eastern United States to Mexico, Belize and Guatemala. It frequents woodlands, gardens, shrublands and wetlands, and has adapted well to suburban environments, where it often visits feeders.
What does the northern cardinal eat?
It feeds mainly on seeds and grains, which it opens with its sturdy conical beak, but also on fruit, berries and insects, especially during breeding. At garden feeders it is particularly attracted to sunflower seeds.
