Scientific Classification
Let’s begin with how the Northern Cardinal is classified in the bird world. Here’s its scientific breakdown:
- Scientific Name: Cardinalis cardinalis
- Family: Cardinalidae
- Order: Passeriformes
- Class: Aves
The Northern Cardinal is a passerine bird, which means it’s a perching songbird—a group known for their vocal talents and diverse species.
Physical Description
One of the most striking features of the Northern Cardinal is its bold and beautiful appearance. You simply can’t miss it.
Size and Shape:
Northern Cardinals are medium-sized songbirds. They measure about 8.3 to 9.1 inches (21–23 cm) in length with a wingspan of 9.8 to 12.2 inches (25–31 cm). Their average weight ranges between 1.5 to 1.7 ounces (42–48 grams).
Plumage and Eye Color:
Males are famous for their vibrant red plumage, which extends from their crest down to their tail. Their face features a distinct black mask that surrounds the beak and eyes. Females, on the other hand, are pale brown with warm reddish tinges on the wings, tail, and crest. Both sexes have dark brown to black eyes.
Crest and Beak:
Northern Cardinals sport a prominent crest on their head, which can raise or lower depending on mood or alertness. Their thick, conical beak is bright orange-red in both males and females, perfect for cracking seeds.
Habitat and Distribution
The Northern Cardinal is a bird of diverse habitats, thriving across many environments in North America.
Habitat:
You’ll often find cardinals in woodlands, gardens, shrublands, wetlands, and even urban backyards. They prefer areas with dense cover for nesting but also open spaces for foraging.
Geographical Range:
These birds are year-round residents in the eastern and central United States, stretching from Maine to Texas. Their range also includes parts of Mexico, Central America, and has expanded north into southern Canada due to warming climates and increased bird feeding.
Cardinals are non-migratory, so once they find a good home, they usually stick around all year long.
Behavior
Northern Cardinals are a delight to observe, both for their visual appeal and their engaging behavior.
Territorial Nature:
These birds are known for their territorial aggression, especially during breeding season. Males will defend their space by singing loudly and even attacking their own reflections in windows or mirrors.
Singing and Communication:
Both males and females sing—a trait that’s not very common in songbirds. Their cheerful whistles, like “cheer-cheer-cheer” or “birdy-birdy-birdy,” are a signature sound of many American neighborhoods.
Social Structure:
Outside of mating season, cardinals may form small flocks, especially in winter when they forage together. During breeding months, however, they’re mostly seen in pairs.
Diet
The Northern Cardinal’s diet is varied and changes slightly with the seasons.
Primary Foods:
Cardinals are granivorous, meaning seeds make up a large part of their diet. They particularly love sunflower seeds, safflower seeds, and millet.
Insects and Fruits:
In warmer months, their diet includes more insects like beetles, caterpillars, and grasshoppers. They also enjoy berries and small fruits, which add moisture and nutrients to their meals.
Feeding Behavior:
At feeders, cardinals prefer platform feeders or ground feeding. They don’t usually cling to hanging feeders, so offering food in the right format can attract more of them to your yard.
Breeding and Nesting
Northern Cardinals are known for their loyal and attentive parenting, making them fascinating to observe during the breeding season.
Mating Habits:
Cardinals form monogamous pairs that often mate for life. Courtship involves males feeding seeds to females beak-to-beak, which is both practical and sweet to witness.
Nesting:
The female usually builds the nest using twigs, leaves, bark strips, and grasses. The nest is often hidden in dense shrubs or low tree branches, around 1 to 15 feet off the ground.
Eggs and Incubation:
She lays 2 to 5 eggs, which are pale with brown speckles. Incubation lasts 11 to 13 days, and the chicks fledge within 9 to 11 days after hatching. The male often helps feed the chicks during and after nesting.
Cardinals can have 2 to 3 broods per year, especially in warmer climates.
Interesting Facts

- No Migration: Unlike many songbirds, Northern Cardinals do not migrate, making them a year-round joy to observe.
- Both Sexes Sing: While most female songbirds don’t sing, female cardinals have a complex vocal range, often singing from the nest to communicate with their mates.
