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. Once the fledgling cardinals have left the nest, the parents will teach them how to fend for themselves and find food. Citation - Watts, B. Old nest accumulation as a possible protection mechanism against search-strategy predators.
Animal Behaviour Cardinals and Cowbirds These birds are often parasitized by the Brown-headed Cowbird. The female Cowbird watches these birds as they build their nest and lay their eggs. While the female Cardinal is away, the Cowbird will visit the nest, remove an egg, and then lay one of her own eggs. Cardinals and Cowbird young are roughly the same size and grow at pretty much the same rate. What this means is, baby Cardinals have a better chance at survival with Cowbirds in the nest than other smaller species.
Never remove a Cowbird egg because the female often returns to check on her egg. If her egg is gone she may cause more problems such as destroying more eggs. Sometimes Cowbirds may remove an egg, lay one of their own eggs, and then pierce remaining eggs. Cardinals are unable to distinquish a Cowbird egg or hatchling from their own. This results in the Cardinals raising the Cowbird all the way to self reliance.
Males will chase other males and females will chase other females from the pairs territories. Cardinals birds often fight with their reflection in house windows and car mirrors. To see what you can do about this behavior check this page for solutions.
In the wild, the adults food consist of insects, spiders, wild fruits, berries, and weed seeds. In winter the Cardinals diet is more plant based which includes seeds and berries in the wild. Some insects under leaves may be found to supplement their diet. Preferring to perch while eating at bird feeders, the ideal bird feeder for them is a the tray feeder style.
You can see what the seed types looks like and learn more about them here: Seed Types. You're likely to notice that these are often the first birds to arrive at the feeders in the morning and the last birds to eat in the evening. Around my home they make their last feeder visit at dusk.
Cardinal birds tend to be very territorial in their feeding habits during the breeding season. If you want to see them at your bird feeders during Spring and Summer, try placing a couple of feeders out of sight from each other. This will allow pairs to feed at the same time without all the chasing that happens. One in your front yard and one in the back works well. In winter they are less territorial around bird feeders. Cardinal Range Map Northern Cardinals are permanent residents throughout their range and do not migrate south.
Their range has been expanding further North. A Heated Birdbath can help provide the drinking and bathing water they need all year. In order to stay warm at night Cardinals will look for dense cover, especially in winter. Tall thick stands of evergreen trees and shrubs offer the best protection for the birds during cold nights.
They may also affect the composition of plant communities because they are seed predators and seed dispersers. Northern cardinals provide food for their predators. They also sometimes raise the chicks of brown-headed cowbirds that are brood parasites and lay eggs in the nests of other birds. This helps local brown-headed cowbird populations. Northern cardinals also provide habitat for many internal and external parasites.
Northern cardinals affect humans by dispersing seeds and eating insect pests such as boll weevils, cutworms, and caterpillars.
They are also an attractive visitor to backyard bird feeders. Northern cardinals appear to have become more common over the past years. Northern cardinals like to live in residential gardens and are attracted to backyard bird feeders. These habitat preferences allow northern cardinals to expand their range and live wherever humans build cities or houses. There are about ,, northern cardinals in the world.
Northern cardinals are also known as common cardinals, cardinal grosbeaks, red-birds, Virginia nightingales, cardinal-birds, cardinal red-birds, Virginia redbirds, crested redbirds and top-knot redbirds.
