Because they are so popular there are a million questions people have about them. According to this article by Penn State University, cardinals are monogamous birds and will typically mate for life. Both the female and male will work together during mating season to build their nest together, which takes about days.
Cardinals are open nested birds and will build their nests out of twigs, pieces of grass, and other plant materials. They prefer building their nests in bushes, dense shrubbery, or low branches that are typically less than 10 feet from the ground. Like most birds cardinals do not use the same nest twice and will build a new nest each year, but may use pieces of old nests to build their new nests.
Cardinals do not migrate and will stay permanent residents throughout their range, even in colder climates. They will however stay in the same general area year round. As for the science behind it, there is a compound found in foods that cardinals like called carotenoids which gives them their red color. Cardinals will enjoy several different types of bird seed including black oil sunflower seeds and safflower seeds as well as cracked corn, peanut pieces and some fruits such as fresh berries.
Se our article on what kind of bird seed cardinals like or our bird seed guide which also shows what types of feeders are best for their preferred bird seed. As I mentioned above, cardinals are open nesters and build their own nests. Any attempts to attract them with a nest box will likely be wasted as cardinals are not cavity nesters and will show no interest in birdhouses. Cardinals will have one to two broods a year , typically two but as many as three on occasion each season.
The female will lay eggs each time and those eggs will hatch in approximately days from the time she lays them. Baby cardinals grow very fast are usually out of the nest in just days. This means from the time the mother cardinal lays her eggs that the babies are off on their own in less than 4 weeks. After the female lays the eggs, she remains on the nest to incubate them for 11 to 13 days. Her brown color allows her to remain undetected by predators and helps keep the young safe.
During this period, the male brings her food. When the chicks hatch, the male may continue to feed the female. Both parents feed the young for the next 25 to 56 days until they learn to feed themselves, or the male may tend to the young while the female starts a new nest. Cardinals eat mostly seeds, grains and fruits.
They sometimes eat spiders and insects, which is almost exclusively what they feed their young. Their strong beaks enable them to crack open even hard seeds such as those from sunflowers. Both male and female cardinals are vocal throughout the year and have a variety of calls. Some scientists believe that a female may use one of these calls while on the nest to notify the male that she and their baby cardinals need to be fed. You can attract cardinals to your yard by providing food, water and shelter.
A variety of seeds, such as sunflower, safflower and cracked corn, as well as apples or peanuts on a platform or hopper feeder near shrubs or other protective foliage will entice the birds. A birdbath or other water feature nearby will provide water and a place to cool off in the summer. Cardinals prefer to build nests in dense bushes or shrubs such as thickets or evergreens. They do not migrate, but instead stay in the same territory year round.

Female birds are usually also attracted to birds with bright plumage. The brighter the plumage, the healthier the male, which indicates that he is well-fed. When the female is looking for a mate, she wants to make sure that she and her chicks will have access to food until the birds can leave the nest. Her tunes are usually more complex and longer because they lure males to mate with her.
Female cardinals also have more interesting plumage, with different shades of bright red and tanned feathers that make them more appealing. Cardinals will become regular visitors to your backyard if you have a continuous supply of fresh seeds. These birds prefer to feed on black oil sunflower seeds and safflower seeds, but you can also buy a mix that offers both types to make sure that all their nutrition needs are met.
Make sure that your feeder has a perching area that allows birds to face their food, or use a tube feeder with a perching tray. This will give the cardinals more room to feed comfortably. Setting up a birdbath in your backyard will make it a popular spot among cardinals and other songbirds. Birds usually prefer having a water source near their nesting space, so they will definitely look for a nearby nest if you keep a birdbath in the shade.
The cool water will be essential for the birds to drink and bathe, especially when the temperature rises. Birds also use the water to preen their feathers for regular maintenance. Make sure that the bath is regularly filled with cool clean water, and keep it away from direct sunlight.
Cardinals will definitely consider nesting in your backyard if you can provide a sheltered area where they can build their nest. These birds prefer to nest near to the ground, so they will look for an area with some overgrowth and abundant camouflage to build their nest and protect their eggs.
This is especially important when watching cardinals in the winter. Your backyard can be an attractive spot to other animals and birds that cardinals might not be comfortable around.
