Cardinals, along with blue jays, are one of the most recognized species of bird in North Louisiana. Like blue jays, cardinals are terrestrial songbirds. Unlike blue jays, cardinals are not known to eat eggs or baby birds. They are omnivores that prefer sunflower seeds and grains to other foods, but also eat berries, flowers, and invertebrates, including spiders and flies.

You’ve probably seen numerous cardinals in your lifetime. Cardinals are finches that live in shrubs and evergreens and cohabitate with humans. They are often in parks and residential areas. Females build the nests, usually in shrubs, but they will also build them in trees and vine tangles. You can often find both male and female cardinals in shrubs and on low tree branches, and on low hanging utility lines near their nests, but please don’t disturb the nest.

Cardinals are unlike most other birds in that they don’t migrate. Unless relocated or chased away, cardinals stay in the same area for their entire lives. If you don’t disturb the nest, you’ll likely be able to enjoy the birds for years. They may be more visible during colder weather, when they may spend more time on the ground foraging.

As is the case with many other birds, male cardinals are brighter than females of the species. The stereotypical cardinal image, think St. Louis Cardinals, is that of a male: a red bird with a black mask that stretches around his eyes and beak. Because cardinals don’t molt, male cardinals stay the same shade of red throughout the year. Likewise, females are soft brown year round. Most females also have a smaller, lighter black mask around their eyes and beak.

Both male and female cardinals have a tufted plume at the top of their heads to indicate the bird’s mood. These birds exhibit aggression by raising their voices and their plumes. When the males are in defensive mode, the plumes on their heads stand up—you could say, they get their feathers in a bunch.

Bad puns aside, these beautiful birds can be incredibly violent toward other birds that enter their territory during the nesting period in the spring and early summer, even to the point of fighting their own reflections. Males will fight any other male cardinal who enters their territory at any time during the year. That beautiful song that the male sings is a warning that this piece of land is his. He sings this song from the highest point in his home tree so that he can see potential intruders.

Cardinals are one of the few songbird species in which the female also sings. For many species, such as the blue jay, songs are a form of territorialism, and are limited to males. Female cardinals, however, often sing from the nest to tell the male when to bring food home.
