While cardinals are primarily non-migratory birds, preferring to stay in their territories year-round, they do engage in occasional short-distance seasonal movements. These movements are in response to changes in food availability and weather conditions. In colder regions, some cardinals may move to lower elevations or areas with more abundant food sources during the winter months. However, they do not embark on extensive migrations like certain songbirds.

Feeding Habits

Cardinals have a diverse diet focused primarily on seeds. They particularly enjoy sunflower seeds, safflower seeds, and millet. Additionally, they consume fruits, berries, and insects, especially during the breeding season when they require additional protein for their young. Cardinals are commonly observed visiting bird feeders, where they readily consume seeds from tray or hanging feeders. They forage on the ground or in low vegetation, using their strong beaks to crack open seeds and extract the nutritious kernel.

Social Dynamics

Cardinals have unique nesting habits, constructing well-hidden and secure nests. Here are some key aspects of cardinal nesting:

  • Cardinals typically build their nests in dense shrubs, bushes, or low tree branches, about 3 to 10 feet above the ground. These locations provide protection from predators and a suitable environment for raising their young.
  • The female cardinal primarily takes responsibility for nest construction. Using twigs, grass, leaves, and bark, she meticulously weaves a cup-shaped structure that serves as the foundation.
  • To ensure comfort and protection, the inside of the nest is lined with softer materials such as feathers, rootlets, and fine grass. This lining cushions the eggs and provides insulation for the hatchlings.
  • Cardinals exhibit remarkable nest-building skills, creating compact and sturdy structures that withstand various weather conditions. In some cases, they may even reuse nests from previous breeding seasons, making necessary repairs and additions.


cardinal bird courtship

Cardinal courtship is a captivating display of visual and auditory communication. Here’s what you need to know:

  • Courtship rituals typically begin in early spring when male cardinals seek to attract a mate. They initiate courtship by singing a variety of songs, showcasing their vocal abilities and establishing their presence.
  • The male’s vibrant plumage plays a crucial role. With their striking red feathers and distinctive crest, male cardinals present an impressive sight as they perch prominently and display their colorful attire.
  • Courtship feeding is another essential aspect. The male cardinal brings food offerings to the female, demonstrating his ability to provide sustenance. This act serves as a bonding gesture between the pair.
  • Male cardinals may also engage in courtship displays, such as fluffing their feathers, spreading their wings, and hopping around the female. These visual demonstrations reinforce their intentions and enhance their chances of successful mating.


Cardinal breeding season typically spans from March to September, during which time the following reproductive processes occur:

  • The female cardinal usually lays a clutch of 3 to 4 eggs, although larger clutches have been observed. The eggs, pale green or bluish-white with brown speckles, provide effective camouflage within the nest.
  • Once the eggs are laid, the female incubates them, assuming the primary responsibility for keeping them warm and ensuring their development. Incubation typically lasts for around 11 to 13 days.
  • After hatching, both parents take on the role of feeding and caring for the nestlings. They tirelessly provide a diet consisting of insects, seeds, berries, and fruits, ensuring the young cardinals receive proper nutrition.
  • The nestlings remain in the nest for approximately 9 to 11 days, during which time they rapidly develop and gain strength. Once capable of flight, they leave the nest, although the parents continue to provide guidance and support as the young cardinals gradually become independent.

Through their intricate nesting, elaborate courtship rituals, and dedicated reproductive efforts, cardinals exemplify remarkable adaptations and behaviors that contribute to their survival and the continuation of their species.
